GLFs in the u,g,r,i and z bands (from left to right). Black crosses are the stacked GLFs with no surface normalization. The red curves are the best Schechter fits corresponding to the black crosses. The vertical red lines indicate the 90% completeness limits. Only galaxies brighter than the 90% completeness limit are taken into account for the fits. The plots for which no Schechter parameters are given in Table 4 are only shown for completeness, but will not be taken into account in the discussion.
