Validation of selection function, sample contamination and mass calibration in galaxy cluster samples
Validation of selection function, sample contamination and mass calibration in galaxy cluster samples
We construct and validate the selection function of the MARD-Y3 sample. This sample was selected through optical follow-up of the 2nd ROSAT faint source catalog (2RXS) with Dark Energy Survey year 3 (DES-Y3) data. The selection function is modeled by combining an empirically constructed X-ray selection function with an incompleteness …
