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.
