Γ	Norm^a		χ²/d.o.f.		Flux^b	90% upper limit^b

	NXB × 1.00	NXB × 0.98	NXB × 1.00	NXB × 0.98	[erg s^-1 cm^-2]

2.18		6.4 × 10^-3	8.0/12	11.9/12	5.3 ± 0.9 (± 3.8) × 10^-12	(< 1.2 × 10^-11)

Notes.

^(a)

Normalization of the power-law model in units of photons keV^-1 cm^-2 s^-1 at 1 keV.

^(b)

The 12–60 keV flux of the power-law component and the 90% upper limit (erg s^-1cm^-2).
