Notes. All errors are at a 90% confidence level. H1, H5, and L are defined as shown in Fig. 3. (a) Photon index. (b) Equivalent hydrogen-absorbing column density. (c) Amplitude of power-law model. (d) Total integrated energy flux over 0.3–7 keV. The bottom part provides the results if NH is frozen to the Galactic value.
