Notes. 

(a)

The parentheses indicate the 1σ statistical uncertainty of the best-fit value. The values without an uncertainty were fixed in the fitting.

(b)

H-equivalent column density of the interstellar extinction.

(c)

Power-law index.

(d)

Flux in the 2.0–8.0 keV range for the soft-band instruments.

(e)

Flux in the 15–50 keV range for the hard-band instruments.

(f)

The goodness of fit with the reduced χ2 (Red-χ2) and degrees of freedom (d.o.f.).
