Upper panel: N_H distribution of the eFEDS AGN with good redshifts (zG ⩾3). The stacked filled histograms display the median N_H distributions of the AGN with 0.2–5 keV net counts >200 (196 sources; yellow), >20 (6181; yellow and green), and >0 (20987; yellow, green, and blue). The red empty histogram displays the median N_H of the sources with well-measured N_H (NHclass = 4). The blue and green empty histograms (with 1-σ errorbars) present the inferred intrinsic N_H distribution using the HBM method for all the AGN with good redshifts (20987) and the subsample with at least 20 counts (6181), respectively. Lower panel: detected fraction measured by simulation as a function of N_H for three subsamples of AGN with 2–10 keV intrinsic luminosity Lx above given logarithmic thresholds and redshift below given thresholds. The three Lx thresholds are selected such that the three subsamples have similar detected fractions at the lowest N_H.
