552	psSphereRot - Galactic to ICRS	David.Robbins@…	Paul Price	"There may be a problem with the specifications for conversions from Galactic to
ICRS.  With the given formulas, I do not get the given Galactic coordinates
detailed on p29 of the current ADD.  For (a,delta) = (0,0), I get the following:

Result is (-107.102,-14.3528), expected (96.3373,-60.1886).

I could be wrong, but I don't see any reason for the difference in values unless
the formulas are incorrect.  If you have another idea though, i'd be happy to
hear it.  
For Ecliptic to ICRS, the ecliptic values all come out correct, except that the
sphere's r (RA) value comes back opposite (negative) of the specified values in
the ADD."	defect	closed	high		PSLib ADD	unspecified	normal	fixed
