SYNOPSYS

void slaEqgal(dr, dd, dl, db)

PARAMETERS

double dr
double dd
double *dl
double *db

DESCRIPTION 


  Transformation from J2000.0 equatorial coordinates to
  IAU 1958 Galactic coordinates.

  (double precision)

Given

     dr,dd       double       J2000.0 RA,Dec

Returned

     *dl,*db     double       Galactic longitude and latitude l2,b2

  (all arguments are radians)

Called

     slaDcs2c, slaDmxv, slaDcc2s, slaDranrm, slaDrange

Note

     The equatorial coordinates are J2000.0.  Use the routine
     slaEg50 if conversion from B1950.0 'FK4' coordinates is
     required.
