Transformation from IAU 1958 Galactic coordinates to B1950.0 'FK4' equatorial coordinates. (double precision)
dl,db double Galactic longitude and latitude l2,b2
*dr,*dd double B1950.0 'FK4' RA,Dec (all arguments are radians)
slaDcs2c, slaDimxv, slaDcc2s, slaAddet, slaDranrm, slaDrange
The equatorial coordinates are B1950.0 'FK4'. Use the routine slaGaleq if conversion to J2000.0 coordinates is required.
