Abstract

We have completed the second part of an extensive survey of faint pairs and groups of galaxies in order to study galaxy evolution at intermediate redshifts. In this paper we present the second catalog of faint interacting galaxies of 49 equatorial fields taken with the Cerro Tololo Inter-American Observatory 4 m prime focus camera. The data set contains 11,297 galaxies within 19 < mR < 22, covering a total area of 2.63 deg2. We have found 1461 isolated pairs and 30 groups with separations 2″ < θ < 6″. Our results confirm the excess of galaxies in pairs and groups found in the first catalog (Infante, de Mello, & Menanteau 1996; de Mello, Infante, & Menanteau 1997). The two catalogs together cover an area of 4.86 deg2 in the sky.
