[AstroPy] Heliocentric Velocity Correction

[Scott Ransom]

Hi Vivienne,

There are heliocentric velocity routines which have many of the major 
observatories in pyslalib (which wraps the GPL'd version of SLALIB). 
See the sla_earth routine for a description (and for a way of getting 
even more accurate values).

PS:  There is a _lot_ of other high-quality functionality in SLALIB 
(which is all wrapped by pyslalib) as well...
