DESCRIPTION


  Transformation from IAU 1958 Galactic coordinates to
  B1950.0 'FK4' equatorial coordinates.

  (double precision)

Given

     dl,db       double       Galactic longitude and latitude l2,b2

Returned

     *dr,*dd     double       B1950.0 'FK4' RA,Dec

  (all arguments are radians)

Called

     slaDcs2c, slaDimxv, slaDcc2s, slaAddet, slaDranrm, slaDrange

Note

     The equatorial coordinates are B1950.0 'FK4'.  Use the
