Comparison of different Schechter curve fits to the DL14 Entire [CII] luminosity function at 3.42 < z < 3.87. This sample includes FARMER LP, the stellar mask and CANDELS factor adjustments. We include the actual fit we chose, as well as fits that are underestimates, overestimates, or were similar. Parameters for these fits are in Appendix D. The left subplot shows the actual Schechter curves themselves, including the two limits of extrapolation we investigate, and the right subplots show the resulting power spectra. The power spectra are mostly similar, except for the ‘overestimate’ case.
