BR photometry of galaxies in low density regions
Listed in IVOA Registry (Virtual Observatory)
We perform detailed surface photometry, based on B- and/or R-band CCD images of 92 faint galaxies.
Description
They are a subsample of those galaxies which were studied by Hopp et al. (1994) in the direction of three nearby voids. We derive integral photometric parameters and radial surface brightness profiles and compare them to those of several faint galaxy samples, located in different environments, and of a bright field galaxy sample.
According to the obtained photometric characteristics, our sample is a mixture of intrinsically bright and faint galaxies, about 60% of them belonging to the bright subsample (M_B_<-19.0). These bright ones show mean characteristics of typical Freeman's disks and are mainly located in the background of the observed voids. The faint subsample (M_B_>=-19.0) has parameters typical for the low-surface-brightness (LSB) galaxies.

There are a few well isolated galaxies both among the bright and faint subsamples.
