Comparison between a 40″ and 80″ source cut below z = 0.5. Both RLFs are corrected with the completeness corrections from Section 4.2. The angular size completeness correction is applied for respectively the 40″ and 80″ angular sizes. This figure contains all sources in the redshift bin 0 < z < 1.0. The 40″ cut selection has 865 sources, while the 80″ cut has 405 sources left. The 1σ error bars are containing z_max errors, Poisson errors, completeness corrections errors, and classification errors.
