Dwarf galaxies in the Virgo cluster. I. The systematic photometric properties of early-type dwarfs.

Abstract

The first results of an extensive photographic surface photometry of dwarf galaxies in the Virgo cluster are presented. The mean radial surface brightness (SB) profiles of 174 dE, 20 dS0, 24 E & S0 and 7 Sa galaxies are surveyed morphologically and analyzed by fitting model profiles
