SLA_RVLG - RV Corrn to Local Group +   +

+
+
ACTION: +
Velocity component in a given direction due to the combination +of the rotation of the Galaxy and the motion of the Galaxy + relative to the mean motion of the local group. +

CALL: +
R = sla_RVLG (R2000, D2000) +

+

+
GIVEN: +
+
+ + + + + +
R2000,D2000RJ2000.0 mean $[\,\alpha,\delta\,]$ (radians)
+

+
RETURNED: +
+
+ + + + + +
sla_RVLGRComponent of solar (n.b.) +motion in direction R2000,D2000 (km s-1)
+

+
NOTE: +
Sign convention: the result is positive when +the Sun is receding from the given point on the sky. +
+

+
REFERENCE: +
