Comparison of our characteristic magnitude M^* and faint end slope α values obtained for the z < 0.67 sample with different richness cuts (black circle, diamond, and square), with those found in the literature. The small cross indicates the field values from Blanton et al. (2001), whereas the other points indicate the values for composite luminosity functions from Goto et al. (2002), Popesso et al. (2006), Rudnick et al. (2009), and Martinet et al. (2015), including all galaxies (black), only red sequence galaxies (red), or only blue cloud galaxies (blue). The high redshift samples are indicated by empty markers. Because of the good agreement between the bands used by the different studies, we did not apply any correction. The values are corrected to our cosmology.
