Redshift selection function of the LBG selection. The completeness per redshift bin was determined from 1000 simulated LBG spectra with different ﹩{\mathrm{EW}}_{\mathrm{Ly}\alpha }﹩, UV continuum slope, and ﹩{r}_{\mathrm{GUNN}}﹩ magnitudes. This is calculated by computing the fraction of the LBG simulated colors, per redshift bin, which was obtained from the selection region. This defines the redshift selection function, which is used for the clustering measurements in Section 4.
