Abstract
In order to analyze the photometric signature of gravitational interactions in spiral and elliptical galaxies, we present results of multicolor broad band (BVRI) surface photometry for a second set of 10 mixed pairs drawn from the Karachentsev Catalogue of Isolated Pairs of Galaxies (KPG). We report total magnitudes and colors, as well as surface brightness, color and geometric ( , PA and  a₄/a) profiles. Most of this subsample have photometric parameters homogeneously derived for the first time. Internal and external data comparisons show consistency within the estimated errors. We find 1 true (E+S) pair and 4 probable (E+S) pairs ((E/S0+S) cases) in the present sample. The remaining objects include 3 lenticular-spiral (S0+S) systems, 1 spiral-spiral (S+S) pair and 1 probable spiral-spiral pair ((S0/Sa+S) case). Four lenticular galaxies show evidence of underlying (perhaps induced) structures like bars/arms. Among the spiral components, an over-representation of early (Sa-Sb) types was found. A brief discussion on the existence of a Holmberg Effect is also presented.
