Comparisons of the number of clusters in point source and extent selected catalogs with eROSITA simulations. Left panel: the fraction of clusters detected in the extent-selected sample vs. the clusters in the point source sample as a function of the counts in R_core (specified as a ML_CTS in the ermldet detection runs) in simulations. Right panel: the cumulative number of clusters in the extended and point source catalogs above a detection flux (ML_Flux in the ermldet runs) limit of 2.7 × 10⁻¹⁴ ergs s⁻¹ cm⁻² measured within R_core (EXT parameter in ermldet outputs).
