Stacked filled histograms: redshift distributions of the eFEDS AGN with spec-z (5287; zG = 5; in blue), with best photo-z (9643; zG = 4; in green), and with good photo-z (6057; zG = 3; in yellow), respectively. The other AGN (1092; zG <3) are displayed in the magenta empty histogram. For sources with photo-z, the redshift PDF is used in plotting. For comparison, we plot the Gaussian distributions centered at z = 1.0 (green dotted line) and z = 1.1 (orange dotted line), which are normalized to the number of AGN with best redshift measurements (zG ⩾4) and good measurements (zG ⩾3), respectively. Both of them have σ = 0.15 in the space of log(l + z).
