SLA_EQGAL - J2000 $\alpha,\delta$ to Galactic

ACTION:

Transformation from J2000.0 FK5 equatorial coordinates to IAU 1958 galactic coordinates.

CALL:

CALL sla_EQGAL (DR, DD, DL, DB)

GIVEN:

$$[\,\alpha,\delta\,]$$ DR,DD

RETURNED:

$$[\,l^{I\!I},b^{I\!I}\,]$$ DL,DB

NOTE:

The equatorial coordinates are J2000.0 FK5. Use the routine sla_EG50 if conversion from B1950.0 FK4 coordinates is required.
