Fractions of sources selected by X-ray spectral properties among the AGN detected in the eFEDS 90%-area region as a function of the 0.2–2.3 keV source detection likelihood. In the upper panel, concerning the N_H measurement with the single-powerlaw model, the AGN are divided into four classes, i.e., 1) uninformative (cyan), 2) unobscured (green), 3) mildly-measured (orange), and 4) well-measured (red). In the lower panel, the purple lines indicate the AGN with spectral measurements of L_X (discussed in Sect. 4.5), and the solid, dashed, and dash-dotted line styles indicated all the AGN, the AGN with good red-shift measurements, and the AGN with the best redshift measurements, respectively.
