Notes. The interstellar absorption is fixed to 9.8 × 1020 cm−2 and the local one to 11.7 × 1020 cm−2 (G21). Errors are at 90%. Fluxes and luminosities are both unabsorbed and computed in the 0.3−10 keV range. The range of the best-fit values from G21 are reported in the first row for an easy reference to the reader. The last column reports whether the source was caught in the hard/high-luminosity (HHL) or soft/low-luminosity (SLL) regime.

(a)

Parameter not constrained.

(b)

Lower limit.
