Histograms showing the distribution of redshift for (a) the 1128 Hα‐selected KISS ELGs and (b) the 486 "normal" galaxies from the CGCG that are located in the same area of the sky. The median redshift is indicated in both plots. Note that the number of KISS ELGs continues to rise up to the cutoff of the filter used for the survey, indicating that the survey is volume limited for the more luminous galaxies. The deficit of ELGs between z = 0.038 and z = 0.054 is due to a large void.
