+SLA_GE50 - Galactic to B1950 $\alpha,\delta$

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

CALL: +
CALL sla_GE50 (DL, DB, DR, DD) +

+

+
GIVEN: +
+
+ + + + + +
DL,DBDgalactic longitude and latitude $[\,l^{I\!I},b^{I\!I}\,]$
+

+
RETURNED: +
+
+ + + + + +
DR,DDDB1950.0 $[\,\alpha,\delta\,]$
+

+
NOTES: +
+
1. +
All arguments are in radians. +
2. +
The equatorial coordinates are B1950.0 FK4. Use the +routine sla_GALEQ if conversion to J2000.0 FK5 coordinates + is required. +
