Notes.
Membership determinations of CGCG and other extended sources are based on velocity measurements of those sources provided in GOLDMine or NED. Membership determination of VCC sources comes from Binggeli et al. (1985, 1993), where in some cases, it is based on galaxy velocity, while in other cases, it is based on the surface brightness versus photographic magnitude (~mB in Vega system) of the galaxy.
