553	psSpherePrecess - inaccuracies	David.Robbins@…	Paul Price	"In testing psSpherePrecess I've noticed some inaccuracy and I'm not sure where
it's coming from.  The following is the output w.r.t. the suggested test cases:

2005:10:15 00:58:59Z|localhost.localdomain|E|testSphereRotPrecess
(tst_psSphereOps.c:341)
    Precess r = 1.95818e-05 not equal to expected = 6.23845
2005:10:15 00:58:59Z|localhost.localdomain|E|testSphereRotPrecess
(tst_psSphereOps.c:367)
    Precess r = -0.0223402 not equal to expected = 6.26083
2005:10:15 00:58:59Z|localhost.localdomain|E|testSphereRotPrecess
(tst_psSphereOps.c:393)
    Precess r = -3.14132 not equal to expected = 3.09662

If you notice, these values are not completely wrong.  The first one for
example, has r =~ 0 and expected ~2*pi.  I will look into this myself as well,
but I'm hoping that someone has insight into this problem for me.  This problem
could be related to, or the same as the previous bug i filed concerning the part
about Ecliptic to ICRS transformation. (bug 552)"	defect	closed	high		PSLib ADD	unspecified	normal	fixed
