SUBROUTINE slGAEQ (DL, DB, DR, DD)
- - - - - -
G A E Q
- - - - - -
Transformation from IAU 1958 galactic coordinates to
J2000.0 equatorial coordinates (double precision)
Given:
DL,DB dp galactic longitude and latitude L2,B2
Returned:
DR,DD dp J2000.0 RA,Dec
(all arguments are radians)
Called:
slDS2C, slDIMV, slDC2S, slDA2P, slDA1P
Note:
The equatorial coordinates are J2000.0. Use the routine
slGE50 if conversion to B1950.0 'FK4' coordinates is
required.
