Sun Mar 24 11:06:11 UTC 2024 - Ben Greiner <code@bnavigator.de>
|
||
|
||
- Update to 1.48
|
||
* Times now support the ``<`` operator, so Python can sort them.
|
||
* For convenience, geoids like :data:`~skyfield.toposlib.wgs84`
|
||
have a new attribute
|
||
:data:`~skyfield.toposlib.Geoid.polar_radius`.
|
||
* You can no longer subtract two positions unless they have the
|
||
same ``.center``. Otherwise, a ``ValueError`` is raised. This
|
||
check has always been performed when you subtract vector
|
||
functions, but it was missing from the position subtraction
|
||
routine.
|
||
* On days that the Sun fails to rise and set in the Arctic and
|
||
Antarctic, the new rising and setting routines now correctly
|
||
set the value ``False`` not only for sunrise but also for
|
||
sunset.
|
||
- Reenable Python 3.12 testing with a new assay
|

|
||
-------------------------------------------------------------------
|
||
Sun Feb 4 11:12:44 UTC 2024 - Ben Greiner <code@bnavigator.de>
|
||
|
||
- Update to 1.47
|
||
* Added faster and more accurate almanac routines
|
||
:func:`~skyfield.almanac.find_risings()` and
|
||
:func:`~skyfield.almanac.find_settings()` and
|
||
:func:`~skyfield.almanac.find_transits()`.
|
||
* Skyfield’s internal table for the ∆T Earth orientation
|
||
parameter has been updated, so that its predictions now extend
|
||
to 2025-01-18.
|
||
* Constellation abbreviations are now consistent between the
|
||
:func:`~skyfield.api.load_constellation_map()` table and the
|
||
:func:`~skyfield.api.load_constellation_names()` list.
|
||
Previously, ``CVn`` and ``TrA`` had been mis-capitalized in the
|
||
list as ``Cvn`` and ``Tra``.
|
||
- Skip testing python312: gh#brandon-rhodes/assay#15 still an issue

|
||
Fri Nov 24 09:46:49 UTC 2023 - Paolo Stivanin <info@paolostivanin.com>
|
||
|
||
- Update to 1.46:
|
||
* The :func:`~skyfield.almanac.oppositions_conjunctions()` routine
|
||
now measures ecliptic longitude using the ecliptic of each
|
||
specific date, rather than always using the J2000 ecliptic,
|
||
which should improve its accuracy by several seconds.
|
||
* Skyfield’s internal table for the ∆T Earth orientation parameter
|
||
has been updated, so that its predictions now extend to 2024-04-13.
|
||
* Bugfix: Skyfield was giving values several kilometers off
|
||
when computing the elevation above ground level of a target that
|
||
was positioned directly above the Earth’s north or south pole.
|
||
* Bugfix: the function skyfield.positionlib.ICRF.is_behind_earth()
|
||
method was incorrectly returning True if the Earth was on the
|
||
line that joins the two satellites, but over on the far side of
|
||
the other satellite where it wasn’t really in the way.
|
||
* The method skyfield.positionlib.ICRF.altaz() now lives on the
|
||
main position class instead of in two specific subclasses.
|
||
If the user mistakenly tries to call .altaz() on an instance
|
||
of the skyfield.positionlib.Astrometric position
|
||
subclass - which previously lacked the method - then a friendly
|
||
exception is raised explaining their error.

Sat Jan 21 11:25:21 UTC 2023 - Ben Greiner <code@bnavigator.de>
|
||
|
||
- Update to v1.45
|
||
* Bugfix: minor planets and comets in Skyfield 1.44 would raise
|
||
an exception if asked for a position in the half of their orbit
|
||
where they are inbound towards their perihelion.
|
||
- Changelog v1.44
|
||
* Skyfield’s internal table for the ∆T Earth orientation
|
||
parameter has been updated, so that instead of including
|
||
measurements only through December 2021 it now knows Earth
|
||
orientation through September 2022.
|
||
* Distance and velocity objects can now be created by calling
|
||
their unit names as constructors, like d = Distance.km(5.0) and
|
||
v = Velocity.km_per_s(0.343).
|
||
* Updated the URL from which the Hipparcos database hip_main.dat
|
||
is downloaded, following a change in the domain for the
|
||
University of Strasbourg from u-strasbg.fr to unistra.fr.
|
||
|
||
-------------------------------------------------------------------
|
||
Thu Aug 11 09:14:22 UTC 2022 - Ben Greiner <code@bnavigator.de>
|
||
|
||
- Update to v1.43.1
|
||
* An attempt at overly clever scripting resulted in a Skyfield
|
||
1.43 release without a setup.py in its .tar.gz; within an hour,
|
||
a Python 2.7 user had reported that Skyfield could no longer
|
||
install. This release is identical to 1.43 but (hopefully)
|
||
installs correctly for everyone!
|
||
- Changelog v1.43
|
||
* Fixed planetary_magnitude() so it works for Saturn even when
|
||
the time is an array rather than a single time; also, improved
|
||
its calculation slightly with respect to Uranus. #739
|
||
* Improved load_comets_dataframe() so that parsing CometEls.txt
|
||
with the most recent version of Pandas doesn’t stumble over the
|
||
commas in the final field of (for example) Halley’s Comet and
|
||
give the error ParserError: Error tokenizing data. C error:
|
||
Expected 12 fields…saw 13. #707
|
||
- Changelog v1.42
|
||
* Added two new position methods phase_angle() and
|
||
fraction_illuminated() that, given an illuminator (usually the
|
||
Sun) as their argument, compute whether the observer is looking
|
||
at the bright side or the dark side of the target body. They
|
||
replace a pair of old functions in the almanac module.
|
||
* The almanac routine moon_nodes() would sometimes skip nodes
|
||
that were closer together than 14.0 days. It has been tightened
|
||
down and should now detect all lunar nodes. #662
|
||
* Time objects now feature a to_astropy() method.
|
||
* The position method to_skycoord() now sets the frame attribute
|
||
of the sky coordinate it returns, and for now only supports
|
||
barycentric and geocentric positions. #577
|
||
- Changelog v1.41
|
||
* Times now support arithmetic: you can add or subtract from a
|
||
time either a number representing days of Terrestrial Time (TT)
|
||
or a Python timedelta which Skyfield interprets as TT days and
|
||
seconds. #568
|
||
* Fixed the .itrs_xyz vector of the geographic position returned
|
||
by the subpoint_of() method. #673
|
||
* Skyfield now uses HTTPS instead of FTP to download JPL
|
||
ephemeris files like de421.bsp. This does risk raising an error
|
||
for users whose machines have out-of-date root certificates.
|
||
But it protects the connection from outside tampering, and will
|
||
keep working if the ssd.jpl.nasa.gov FTP service is ever shut
|
||
down — as happened earlier this year to FTP on NASA’s
|
||
cddis.nasa.gov server. #666
|
||
- Changelog v1.40
|
||
* Extended the planetary_magnitude() routine to work with all the
|
||
major planets, which upgrades it from a prototype feature to a
|
||
production feature of Skyfield.
|
||
* The subpoint() method has been deprecated, because users
|
||
reported that its name was a poor match for its behavior. Four
|
||
new methods have replaced it: latlon_of(), height_of(),
|
||
geographic_position_of(), and subpoint_of(). #644
|
||
* Added a timescale method linspace(). #617
|
||
* The oppositions_conjunctions() routine, which was originally
|
||
designed only for planets, can now also handle the Moon (which
|
||
moves from opposition to conjunction much faster).

|
||
|
||
- Update to 1.39
|
||
* The Angle.dstr() and Angle.hstr() methods now accept a
|
||
format= argument that lets callers override Skyfield’s default
|
||
angle formatting and supply their own; see Formatting angles.
|
||
#513
|
||
* The prototype planetary_magnitude() function now works not
|
||
only when given a single position, but when given a vector of
|
||
several positions.
|
||
- Release 1.38
|
||
* Replaced the old historic ∆T table from the United States
|
||
Naval Observatory with up-to-date splines from the 2020 release
|
||
of the extensive research by Morrison, Stephenson, Hohenkerk,
|
||
and Zawilski and also adjusted the slope of Skyfield’s
|
||
near-future ∆T estimates to make the slope of ∆T much less
|
||
abrupt over the coming century.
|
||
* Added a full reference frame object for the TEME reference
|
||
frame used by SGP4 Earth satellite elements.
|
||
- Release 1.37
|
||
* Added a frame_latlon_and_rates() method that can compute the
|
||
rates at which angles like altitude and azimuth, or right
|
||
ascension and declination, are changing.
|
||
* Accepted a contributor’s helpful fix for a rounding error that
|
||
had slightly shifted a few constellation boundaries. #548
|
||
* The Time tuple utc and method utc_strftime() are now backed by
|
||
the same math, so they always advance to the next calendar day
|
||
at the same moment. This makes it safe to mix values returned
|
||
by one of them with values returned by the other. #542
|
||
* Vector subtraction now returns the position subclass specific
|
||
to the resulting vector’s center. #549
|
||
- Release 1.36
|
||
* Tweaked several lines of code that build NumPy arrays to avoid
|
||
a new deprecation warning Creating an ndarray from ragged
|
||
nested sequences (which is a list-or-tuple of
|
||
lists-or-tuples-or ndarrays with different lengths or shapes)
|
||
is deprecated. NumPy no longer wants to accept a simple
|
||
constant like 0.0 where the resulting array needs a whole row
|
||
of zeros. #536
|
||
* Added an hadec() position method that returns hour angle and
|
||
declination. #510
|
||
* The default str() and repr() strings for geographic positions
|
||
have been streamlined, and no longer raise ValueError when
|
||
elevation is an array. They now show simple decimals instead
|
||
of splitting degrees of longitude and latitude into minutes
|
||
and seconds; always show elevation, even if zero; properly
|
||
format NumPy arrays; and abbreviate long arrays. #524
|
||
* Fixed Angle.dstr() and Angle.hstr() to return an array of
|
||
strings when the angle itself is an array. #527

Fri Jan 1 23:53:33 UTC 2021 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to 1.35
|
||
* Deprecated the old Topos class, which not only featured
|
||
a clunky interface but hid from users the fact that
|
||
Skyfield was generating IERS2010 positions from latitude
|
||
and longitude when in fact nearly all users want WGS84
|
||
positions. Users are now encouraged to supply latitude
|
||
and longitude to the
|
||
:meth:`~skyfield.toposlib.Geoid.latlon()` method of
|
||
either the :data:`~skyfield.toposlib.wgs84` object or the
|
||
:data:`~skyfield.toposlib.iers2010` object. Related
|
||
discussion: #372
|
||
* The two new geoid objects
|
||
:data:`~skyfield.toposlib.wgs84` and
|
||
:data:`~skyfield.toposlib.iers2010` have also provided a
|
||
happy new home for the
|
||
:meth:`~skyfield.toposlib.Geoid.subpoint()` method —
|
||
which was previously stranded over on the
|
||
:class:`~skyfield.positionlib.Geocentric` class, where it
|
||
couldn’t be used with positions of other classes that
|
||
might be centered at the geocenter. (The old method will
|
||
remain in place to support legacy code, but is
|
||
discouraged in new applications.)
|
||
* The effects of :ref:`Polar motion` — if configured —
|
||
are now included both when computing the position in
|
||
space of an Earth latitude and longitude, and when
|
||
determining the latitude and longitude beneath a
|
||
celestial position.
|
||
* Added :func:`~skyfield.api.load_constellation_names()`.
|
||
* The :meth:`~skyfield.timelib.Time.utc_jpl()` method now
|
||
correctly designates its return value as UTC instead of
|
||
the ambiguious UT. #515
|
||
- Refreshed finals2000A.all
|
||
|
||
-------------------------------------------------------------------
|
||
Tue Dec 15 17:59:15 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to v1.34
|
||
* The position classes have gained methods frame_xyz(),
|
||
frame_xyz_and_velocity(), frame_latlon(), and
|
||
from_time_and_frame_vectors() that work with a new
|
||
library skyfield.framelib to offer a number of familiar
|
||
reference frames. These replace the existing ad-hoc
|
||
position methods for ecliptic and galactic coordinates,
|
||
which are now deprecated (but will continue to be
|
||
supported). See Coordinates in other reference frames.
|
||
* Added support for IERS Polar Motion 𝑥 and 𝑦.
|
||
* Added a method lst_hours_at() that computes Local
|
||
Sidereal Time.
|
||
* A new almanac routine moon_phase() returns the Moon
|
||
phase as an angle where 0° is New Moon, 90° is First
|
||
Quarter, 180° is Full, and 270° is Last Quarter. #282
|
||
* Almanac search routines that previously returned a
|
||
Boolean true/false array now return an integer 0/1
|
||
array instead, to work around a new deprecation warning
|
||
in NumPy which, for example, would have outlawed using
|
||
the Boolean array from moon_nodes() to index into the
|
||
MOON_NODES list that provides a name for each node. #486
|
||
* The undocumented columns magnitude_H and magnitude_G
|
||
in the Minor Planet Center comets dataframe have been
|
||
renamed magnitude_g and magnitude_k following further
|
||
research on the file format (which does not itself
|
||
document which magnitude model is intended). #416
|
||
- add finals2000A.all to testdata

-------------------------------------------------------------------
|
||
Fri Nov 20 23:03:34 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to v1.33
|
||
* Fix: running ``load.timescale(builtin=False)`` was raising an
|
||
exception ``FileNotFoundError`` if the ``finals2000A.all`` file was
|
||
not already on disk, instead of downloading the file automatically.
|
||
`#477 <https://github.com/skyfielders/python-skyfield/issues/477>`_
|
||
- v1.32
|
||
* A new :func:`~skyfield.eclipselib.lunar_eclipses()` routine finds
|
||
lunar eclipses and determines their degree of totality.
|
||
`#445 <https://github.com/skyfielders/python-skyfield/issues/445>`_
|
||
* The almanac module’s new :func:`~skyfield.almanac.meridian_transits()`
|
||
routine can find the moments at which a body transits the meridian and
|
||
antimeridian.
|
||
`#460 <https://github.com/skyfielders/python-skyfield/issues/460>`_
|
||
* Fix: the :func:`~skyfield.searchlib.find_minima()` function was
|
||
ignoring its ``epsilon`` and ``num`` arguments and always using the
|
||
default values instead.
|
||
`#475 <https://github.com/skyfielders/python-skyfield/pull/475>`_
|
||
|
||
* Fix: the ``.epoch`` attribute of Earth satellite objects that were
|
||
built using :meth:`~skyfield.sgp4lib.EarthSatellite.from_satrec()`
|
||
was, alas, a half-day off.
|
||
`#466 <https://github.com/skyfielders/python-skyfield/issues/466>`_
|
||
|
||
* Fix: the :class:`~skyfield.toposlib.Topos` constructor arguments ``x``
|
||
and ``y``, which never worked properly, have been deprecated and are
|
||
now ignored.
|
||
|
||
1.31 — 2020 October 24
|
||
----------------------
|
||
|
||
* Skyfield now uses the International Earth Rotation Service (IERS) file
|
||
``finals2000A.all`` for updated ∆T and leap seconds. The USNO is no
|
||
longer updating the files ``deltat.data`` and ``deltat.preds`` that
|
||
previous versions of Skyfield used, and the ``cddis.nasa.gov`` server
|
||
from which they were fetched will discontinue anonymous FTP on 2020
|
||
October 31. See `downloading-timescale-files`.
|
||
`#452 <https://github.com/skyfielders/python-skyfield/issues/452>`_
|
||
`#464 <https://github.com/skyfielders/python-skyfield/issues/464>`_
|
||
|
||
* The comets dataframe built from the MPC file ``CometEls.txt`` now
|
||
includes the ``reference`` column, so users can tell which orbit is
|
||
most recent if there are several orbits for a single comet. (For
|
||
example, the file currently lists two C/2020 F3 (NEOWISE) orbits.)
|
||
The comet examples in the documentation now build a dataframe that
|
||
only includes the most recent orbit for each comet.
|
||
`#463 <https://github.com/skyfielders/python-skyfield/issues/463>`_
|
||
|
||
* Two new methods :meth:`~skyfield.iokit.Loader.days_old()` and
|
||
:meth:`~skyfield.iokit.Loader.download()` make it simple to download a
|
||
fresh copy of a file if the copy on disk is older than you would like.
|
||
|
||
1.30 — 2020 October 11
|
||
----------------------
|
||
|
||
* The various ``strftime()`` Skyfield methods now support the ``%j``
|
||
day-of-year format code.
|
||
|
||
* Fix: the new Julian calendar support broke support for out-of-range
|
||
month numbers, wrapping them into the current year instead of letting
|
||
them overflow into subsequent years.
|
||
`#461 <https://github.com/skyfielders/python-skyfield/issues/461>`_
|
||
|
||
* Fix: a stray debugging ``print()`` statement was stranded in ``t.dut1``.
|
||
`#455 <https://github.com/skyfielders/python-skyfield/issues/455>`_
|
||
|
||
* The :class:`~skyfield.timelib.Time` object, if manually instantiated
|
||
without a Julian date fraction, now provides a fraction array with
|
||
dimensions that match the Julian date argument.
|
||
`#458 <https://github.com/skyfielders/python-skyfield/issues/458>`_

|
||
Sat Sep 26 08:13:08 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to version 1.29
|
||
* Fix: the new Julian calendar feature was raising an
|
||
exception in the calendar methods like
|
||
`skyfield.timelib.Time.tt_calendar()` if the time
|
||
object was in fact an array of times. #450
|
||
* Fix: trying to iterate over a time object would raise an
|
||
exception if the time was created through
|
||
`~skyfield.timelib.Timescale.ut1()`.
|
||
- Version 1.28
|
||
* Broken URL: Because the VizieR archive apparently decided
|
||
to uncompress their copy of the hip_main.dat.gz Hipparcos
|
||
catalog file, the old URL now returns a 404 error. As an
|
||
emergency fix, this version of Skyfield switches to their
|
||
uncompressed hip_main.dat. Hopefully they don’t compress
|
||
it again and break the new URL! A more permanent solution
|
||
is discussed at: #454
|
||
* To unblock this release, removed a few deprecated pre-1.0
|
||
experiments from April 2015 in skyfield.hipparcos and
|
||
skyfield.named_stars that broke because the Hipparcos
|
||
catalog is no longer compressed; hopefully no one was
|
||
using them.
|
||
* In a sweeping internal change, the
|
||
`~skyfield.timelib.Timescale` and
|
||
`~skyfield.timelib.Time` objects now offer support
|
||
for the Julian calendar that’s used by historians for
|
||
dates preceding the adoption of the Gregorian calendar in
|
||
1582. See choice of calendars if you want to turn on
|
||
Julian dates in your application. #450

-------------------------------------------------------------------
|
||
Wed Sep 16 09:53:08 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to version 1.27
|
||
* The printed appearance of both vectors and of vector
|
||
functions like Earth locations and Earth satellites
|
||
have been rewritten to be more informative and
|
||
consistent.
|
||
* Added compute_calendar_date() which lets the caller
|
||
choose the Julian calendar for ancient dates instead of
|
||
always using the proleptic Gregorian calendar. This
|
||
should be particularly useful for historians.
|
||
* Added J() that builds a time array from an array of
|
||
floating point years. #436
|
||
* Added four new strftime methods for the non-UTC
|
||
timescales (#443). All four of them support %f for
|
||
microseconds, and provide a reasonable default format
|
||
string for callers who don’t wish to concoct their own:
|
||
tai_strftime()
|
||
tt_strftime()
|
||
tdb_strftime()
|
||
ut1_strftime()
|
||
* Thanks to several fixes, comets and asteroids with
|
||
parabolic and hyperbolic orbits should now raise fewer
|
||
errors.
|
||
* The prototype planetary_magnitude() can now return
|
||
magnitudes for Uranus without raising an exception. The
|
||
routine does not yet take into account whether the
|
||
observer is facing the equator or poles of Uranus, so
|
||
the magnitude predicted for the planet will only be
|
||
accurate to within about 0.1 magnitudes.

Sun Aug 2 11:51:04 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to version 1.26
|
||
* The official ∆T files on NASA’s FTP server have stopped receiving
|
||
updates — they have no new data beyond February, the start of the
|
||
global pandemic. Unless they are updated by next February, older
|
||
versions of Skyfield will unfortunately download the files all over
|
||
again every time `skyfield.iokit.Loader.timescale()` is called
|
||
(unless the ``builtin=True`` parameter is provided). To make Skyfield
|
||
less fragile going forward:
|
||
1. The loader’s `skyfield.iokit.Loader.timescale()` method now
|
||
defaults to ``builtin=True``, telling it to use the ∆T and leap
|
||
second files that ship with Skyfield internally. To download new
|
||
∆T files from NASA and the leap second file from the International
|
||
Earth Rotation Service, specify ``builtin=False``.
|
||
2. The concept of an “expired” file has been removed from ``load()``.
|
||
Skyfield is now much simpler: if a file with the correct name
|
||
exists, Skyfield uses it. See `downloading-timescale-files`
|
||
if you still want your application to check the age of your
|
||
timescale files and automatically download new ones.
|
||
* The `ICRF.separation_from()` method now officially supports the
|
||
combination of an array of positions with a single reference position!
|
||
Its previous support for that combination was, alas, accidental, and
|
||
was broken with the 1.23 release.

|
||
`#424 <https://github.com/skyfielders/python-skyfield/issues/424>`
|
||
* A prototype `skyfield.magnitudelib.planetary_magnitude()`
|
||
routine has been added with support for several planets.
|
||
`#210 <https://github.com/skyfielders/python-skyfield/issues/210>`
|
||
* The ``utc`` timezone that Skyfield returns in Python datetimes is now
|
||
either the Python Standard Library’s own UTC object, if it supplies
|
||
one, or else is defined by Skyfield itself. Skyfield no longer
|
||
silently tries importing the whole ``pytz`` package merely to use its
|
||
UTC object — which also means that the timezone returned by Skyfield
|
||
longer offers the non-standard ``localize()`` method.

Sat Jul 25 11:43:28 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to version 1.25
|
||
* Added skyfield.data.stellarium.parse_constellations()
|
||
and skyfield.data.stellarium.parse_star_names()
|
||
to load Stellarium star names and constellation lines.
|
||
Constellation lines are featured in a new example script
|
||
neowise-chart that produces a finder chart for
|
||
comet C/2020 F3 NEOWISE.
|
||
* The Hipparcos star catalog should now load faster, having
|
||
switched behind the scenes to a higher performance Pandas
|
||
import routine.
|
||
* Fixed the ability of skyfield.timelib.Timescale.utc()
|
||
to accept a Python datetime.date object as its argument.
|
||
#409
|
||
* Slightly lowered the precision of two tests when they
|
||
detect that Python is compiled for a 32-bit processor, so
|
||
the test suite can succeed when contributors package
|
||
Skyfield for 32-bit Linux. #411
|
||
- use upstreams custom test runner 'assay'
|
||
* The runner does not have any releases yet. No package
|
||
available, so use assay-master-252.79f5d78.tar.gz directly
|
||
* drop skyfield-pr405-replace-assay-by-pytest.patch
|
||
* gh#brandon-rhodes/assay#6, gh#skyfielders/python-skyfield#405
|
||
- the unit test expect a truncated hipparcos catalog

|

Wed Jul 22 14:13:46 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to Version 1.24
|
||
* Added methods :meth:`~skyfield.timelib.Timescale.from_datetime()`
|
||
and :meth:`~skyfield.timelib.Timescale.from_datetimes()` to
|
||
the :class:`~skyfield.timelib.Timescale` class, to
|
||
better advertise the ability to build a Skyfield time
|
||
from a Python datetime — an ability that was previously
|
||
overloaded into the year parameter of the
|
||
:meth:`~skyfield.timelib.Timescale.utc()` method (where
|
||
it is still supported for backwards compatibility, but
|
||
no longer documented).
|
||
* Fix: improved the accuracy with which velocity is
|
||
converted between the Earth-fixed ITRF frame that rotates
|
||
with the Earth and the inertial GCRS frame that does not.
|
||
In particular, this should make Earth satellite
|
||
velocities more accurate.

Fri Jul 10 14:51:52 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to Version 1.23
|
||
* Added `kepler-orbits` support for generating the positions of comets and
|
||
asteroids from Minor Planet Center data files.
|
||
* Added `skyfield.positionlib.ICRF.is_behind_earth()` to determine whether a
|
||
celestial object is blocked from an Earth satellite’s view by the Earth
|
||
itself.
|
||
* Replaced the awkward and hard-to-explain rough_period search parameter with
|
||
the conceptually simpler step_days parameter, and updated the instructions
|
||
in `searches` to match.
|
||
* Made the `skyfield.iokit.Loader.load.tle_file()` import method less strict
|
||
about Earth satellite names: any text on the line before two lines of TLE
|
||
data is now saved as the satellite name. A parameter skip_names=True turns
|
||
this off if, for particular TLE files, this leads to unwanted text being
|
||
saved
|
||
- directly copy downloaded testfiles as sources
|
||
- move skyfield-openSUSE-comparefloat.patch to skyfield-PR404-comparefloat.patch

|
||
- move skyfield-openSUSE-replace-testrunner.patch to
