Comparisons between the real (blue) and the mock (orange) eFEDS data. Panel 1 compares the event PI (photon energy) distributions. Panel 2 compares the distributions of the 0.2–2.3 keV background map value (counts/pixel) in each pixel. The dotted vertical line corresponds to the median values of the two data sets, which are identical. Panels 3–4 display the total number of sources in the 0.2–2.3 keV single-band-detected catalog above a given count rate (panel 3) or above a given detection likelihood (DET_LIKE; panel 4) for point sources (“PNT”; EXT_LIKE=0; solid lines) and extended sources (“EXT”; EXT_LIKE>0; dashed lines), respectively. Panel 5 displays the extent likelihood (EXT_LIKE) distribution of the single-band-detected extended sources. Panel 6 displays the 2.3–5 keV (band 3) count rate of sources that are detected in this band (DET_LIKE_3 > 6) from the three-band detection. The number of sources is printed in the label of each entry.
