The distance of the Fornax Cluster based on Globular Cluster Luminosity Functions

Abstract

We present Globular Cluster Luminosity Functions for four ellipticals and one S0-Galaxy in the Fornax cluster of galaxies, derived from CCD photometry in V and I. The averaged turnover magnitudes are $V_{TO}=23.80\pm 0.06$ and $I_{TO}=22.39\pm 0.05$, respectively. We derive a relative distance modulus $(m-M{)}_{Fornax}-(m-M{)}_{M87}=0.08\pm 0.09$ mag using the turnover of M87 based on HST data.
