- 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
- Define skip_python36 for TW, because current astropy needs
Python >=3.7
