Multi-spectral study of a new sample of Blue Compact Dwarf Galaxies -: II.: B and R surface photometry of 22 southern objects

We present the results of surface photometry on a new sample of Blue Compact Dwarf galaxies (BCDGs), in continuation to a previous paper (Doublier et al. 1997, hereafter Paper I). The 22 galaxies (plus two companions) discussed in the present paper have been selected in the Southern Hemisphere, from several lists. An atlas containing isophotal maps, surface brightnesses and B - R color profiles of the sample is given, together with the tables containing the photometric parameters. The results are consistent with those obtained in Paper I fur objects selected from the Byurakan Surveys in the Northern hemisphere. Similarly, we find about one fourth of the BCDGs showing a dominant r(1/4) brightness distribution component, one fourth of the BCDG showing a dominant exponential surface brightness profile, and about half of them show composite brightness distributions. Integrated properties, colors; mean surface brightnesses and luminosity-radius relations are investigated and discussed for the objects presented in this paper and Paper I. We found that r(1/4) BCDGs tend to show a different behaviour compared to the exponential BCDGs, with respect to colors, compactness and luminosity-radius relations. We also include a brief study of the surroundings of the galaxies, where we find several candidate companions.
