Same as Fig. 11, but showing the best fits to the data with the accretion-heated pure He atmosphere models of various accretion luminosities Lacc/LEdd = 0 (solid line), 0.03 (dotted), and 0.05 (dashed) (Suleimanov et al. 2017a). The vertical dashed line gives the Eddington flux for the model with Lacc/LEdd = 0.03.
