摘要：

We derive I-band luminosity functions for galaxies in Abell 426 (Perseus and Abell 539, two rich, low Galactic latitude clusters at moderate redshift. Cluster members are selected via the color-magnitude relation for bright galaxies. We find alpha = - 1.56 +/- 0.07 for Perseus over the range - 19.4 < M-I < - 13.4 (15 < I < 21) and alpha = -1.42 +/- 0.14 for - 18.5 < M-I < - 14 (17 < I < 21.5) for A539. These luminosity functions are similar to those derived in Virgo and Fornax, weakly supporting claims for the existence of a universal luminosity function for galaxies in clusters.
