- 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
