+SLA_EG50 - B1950 $\alpha,\delta$ to Galactic +

+
+
ACTION: +
Transformation from B1950.0 FK4 equatorial coordinates to +IAU 1958 galactic coordinates. +

CALL: +
CALL sla_EG50 (DR, DD, DL, DB) +

+

+
GIVEN: +
+
+ + + + + +
DR,DDDB1950.0 $[\,\alpha,\delta\,]$ (radians)
+

+
RETURNED: +
+
+ + + + + +
DL,DBDgalactic longitude and latitude $[\,l^{I\!I},b^{I\!I}\,]$ (radians)
+

+
NOTE: +
The equatorial coordinates are B1950.0 FK4. Use the +routine sla_EQGAL if conversion from J2000.0 FK5 coordinates + is required. +
