Abstract

We present a simple analytic model to deproject 2-d luminosity functions (LF) of cluster galaxies; We apply this model to deproject the Us of the Coma cluster measured by Beijersbergen et al. 2001. We demonstrate that the shapes of the Us change after deprojection. The corrections are large enough to change the previously observed trend of increasing faint end slopes with increasing distance to the cluster center. The weighted U, B, and r band slopes of the deprojected Us show only a weak steepening with increasing projected cluster radius. It is therefore essential to correct Us for projection effects.
