Hi all,
I wrote the library. It's mostly trivial, yet might be handy - should't
we include it in astropy?
Source:
https://github.com/RTS2/rts2/blob/master/python/rts2/mpcephem.py
Checks:
https://github.com/RTS2/rts2/blob/master/checks/check_python_mpcephem
+check data:
https://github.com/RTS2/rts2/blob/master/checks/data/mpecephem_ida
I know it does not parse the header and assumes Sky speed/PA format,
but I will work on this.
