File Name : Name of Source Table to save.

Source Name : Name of a source which you observe.

Velocity : Radial velocity of the source.
 
Frame : Frame of the velocity.

Definition : Definition of the velocity.

  • Radio : Vradio = (1 -¦Í/¦Í0)c
        • ¦Í: observed frequency
        ¦Í0 : rest frequency
         c : light speed
