B, V, I photometry of 20 dwarf irregular galaxies within 10 Mpc

CCD photometry is presented for 20 dIrr galaxies situated in the nearby complexes CenA/M83, and CVnI as well as in the general field of the Local Volume. We present integrated magnitudes of the galaxies in B, V, I bands and also surface brightness profiles to a median isophote mu(B) similar to 28 mag arcsec(-2). The popular Sersic parametrization of surface brightness profiles generally does a poor job of simultaneously fitting the inner cores and outer exponential surface brightness fall-offs observed in many of our targets. The observed sample is a part of a general project to image about 500 nearby (D < 10 Mpc) dwarf galaxies in multiple bands.
