palRvlg palRvlg - Velocity component in a given direction due to Galactic rotation and motion of the local group

Description:
This function returns the 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. The result is $+$ve when the Sun is receding from the given point on the sky.

Invocation:
double palRvlg( double r2000, double d2000 )

Arguments:

r2000 = double (Given)
J2000.0 mean RA (radians)
d2000 = double (Given)
J2000.0 mean Dec (radians)

Returned Value:

Component of SOLAR motion in direction R2000,D2000 (km/s).
