Datatype: GPO

This datatype gpo refers to mean radial velocity obtained with Fehrenbach objective prism. GPO means "Grand prism objectif".

Most published GPO radial velocities are only mean values, because the individual data have not always been published. If this was the case, they are recorded with the other individual radial velocities (irv).
