Galaxy luminosity functions for Abell 1758 North in the g′ (top) and r′ (bottom) bands, in logarithmic scale. The blue and red points correspond to the two galaxy selections (see text), and the best Schechter function fits are drawn with the same colours as the corresponding points. At bright magnitudes the points exactly coincide, and because the blue points were plotted after the red ones, they appear blue. Error bars are 4 times the Poissonian errors on galaxy counts (see text).
