SDSS_DR10.GalaxyVol* tables

This is a volume-limited subset of the Galaxy table. The table contains only parameters that depend on the group distance which the galaxy belongs to.

Galaxy ID galid is the same as in the Galaxy table. For each GalaxyVol* table thare is a corresponding GalGroupVol* table.
