Photon index distribution of the NLS1 DR12 eRASS1 sample. The solid line shows the results obtained from a simple power-law fit with N_H fixed to the Galactic value for the entire sample. The dashed line shows only the results obtained where the fit with N_H as a free parameter was successful. For the latter subsample, the distribution is shifted to slightly higher photon indices. The solid vertical lines mark the means at 2.6 (N_H fixed) and 3.9 (N_H free). Some increase in steepness is realistic due to the degeneracy as N_H, gal gives a lower bound to the true value of N_H. The dotted vertical line is the typical slope of X-ray-emitting AGN in the eFEDS field, as shown by Liu et al. (2022).
