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