Abstract:
We present BVI photometry of 190 galaxies in the central 4x3deg2
region of the Fornax cluster observed with the Michigan Curtis Schmidt
Telescope. Results from the Fornax Cluster Spectroscopic Survey (FCSS)
and the Flair-II Fornax Surveys have been used to confirm the
membership status of galaxies in the Fornax Cluster Catalogue (FCC,
Cat. VII/180). In our catalogue of 213 member galaxies, 92 (43 per
cent) have confirmed radial velocities.
