[Spice_discussion] Heliographic Rotating Coordinate System in SPICE

[William Thompson]

That particular coordinate system is implemented through the IAU_SUN coordinate 
frame, e.g.

cspice_spkezr, sc, et, 'IAU_SUN', corr, 'Sun', state, ltime

By the way, a number of other heliophysical coordinate frames are implemented 
via the following frame file:
