Catalog Service: Southern binary galaxies radial velocities
Description
We present spectrophotometry of a sample of 26 Southern binary galaxies. 17 pairs were confirmed to be physically associated with typical separation of 136h^-1^kpc. Pairs with velocity difference {DELTA}V>=600km/s are probably not physically bound. A comparison with field galaxies suggests that galaxies in pairs tend to have a younger population probably stimulated by tidal interaction. No correlation between the young population and projected separation was found. This table contains the quantities derived from the spectral data.
