(d*)

The values for the cyclotron line depths are 14  ±  4 and 18  ±  4 for the Mar. 2006 and Sep. 2010 observations, respectively.

(e)

With normBB = /, where d10 is the distance in units of 10 kpc, varying from 0.5–1.3 (assuming the 5–13 kpc distance range reported for this source).

(f)

 × 10-9 erg cm-2 s-1 (0.5–100 keV), based on the XIS 03 flux calibration; XIS 03 is a combined spectrum from XIS 0 and XIS 3.

(g)

Intercalibration factors (PIN/XIS 03 and GSO/XIS 03). The GSO/XIS 03 factor was fixed to the value obtained for the second observation since it could not be well constrained.
