- 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.
