Notes. All quoted uncertainties correspond to the 1σ confidence interval;

(a)

dimensions of the extraction region: semi-major and minor axes for the Full region and radius for the Core region;

(b)

effective extraction area on the detector (PN), taking excluded point sources, bad pixels/columns, and chip borders into account;

(c)

photon index of the power-law model;

(d)

unabsorbed integral flux;

(e)

value of χ2 divided by the number of degrees of freedom.
