Query: A Catalog of Faint Interacting Galaxies in Pairs and Groups   We have carried out an extensive survey of faint galaxies in order to examine
the rise in the merger rate with redshift and to study the statistical
relations between close interacting galaxies and the field galaxy population.
In this paper we present the catalogs of faint pairs and groups of galaxies of
46 equatorial fields taken with the CTIO 4m prime focus. The data set contains
73,988 galaxies covering a total area of 2.23~deg$^{2}$. We have found 1751
isolated pairs and 30 groups of galaxies within $19<m_{R}<22$ and
$2''<\theta<6''$ in this area. Our results show clearly an increase in pairs
and groups of galaxies in comparison to a randomly generated catalog.
