Fig. 4.
Relations between black-body temperature (left) and absorbed X-ray luminosity (center) values computed with NH being a free parameter of X-ray spectral fit (y-axes) and for NH computed from Eq. (5) with f = 0.5 (x-axes). Right-hand panel: relation between bets-fit NH and NH computed from Eq. (5). Only sources with net counts ≥200 are shown. Errors are 1σ. See Sect. 5.1 for more details.
