A. Schroder et N. Visvanathan, NEW APERTURE PHOTOMETRY FOR 217 GALAXIES IN THE VIRGO AND FORNAX CLUSTERS, Astronomy & Astrophysics. Supplement series, 118(3), 1996, pp. 441-451
We present photo electric multi-aperture photometry in UBVRI of 171 an
d 46 galaxies in the Virgo and Fornax clusters, respectively. Many of
the galaxies have not been observed in at least one of these passbands
before. We discuss the reduction and transformation into the Cousins
photometric system as well as the extinction coefficients obtained bet
ween 1990 and 1993.
