Scientific paper

Photometric parameters derived from surface photometry of dwarf elliptical galaxies are used to determine the relative distance between the Virgo, Fornax, and Centaurus clusters. The study uses a sample of about 25 dwarf elliptical galaxies in each cluster. With Virgo as the fiducial cluster, it is found that R(Fornax)/R(Virgo) = 0.93 + or - 0.07 and R(Centaurus)/R(Virgo) = 1.91 + or - 0.07. The results are in good agreement with those obtained by Aaronson et al. (1989) using the IR Tully-Fisher relation.
