Notes.

^(a)

Observatory name: S = Suzaku/XIS, B = Swift/BAT, C = Chandra/ACIS, X = XMM-Newton/EPIC, SX = Swift/XRT.

^(b)

The best-fit models: A = N_H*PL, B = N_H*PL + Gauss, C = Pcfabs*PL + Gauss, D = Pcfabs*PL + Gauss + Pexrav, E = N_H*PL + Gauss + Pexrav + Th, F = Pcfabs*PL + Gauss + Pexrav + Th. All models include the galactic absorption, not shown here for simplicity.

^(c)

Source-intrinsic column density and primary power-law photon index (p indicates a value pegged at the lower/upper limit of 1.5/1.9).

^(d)

Where modeled, the fraction of the scattered component relative to the intrinsic power law.

^(e)

Centroid energy and equivalent width with respect to the whole continuum of the Fe fluorescence Kα line at the rest frame of the source redshift.

^(f)

Y = present, N = not found, / = not modeled.

^(g)

(obs) = observed, (unabs) = absorption corrected, (pow) = power law.

^(h)

1 = Isobe et al. (2002), 2 = Evans et al. (2006), 3 = Winter et al. (2009a), 4 = here.
