Notes.

^(a)

This cut-off value is obtained when applying the zcutoffpl model in xspec with Γ fixed to a value of 1.9.

^(b)

L_x is measured in the 2–10 keV rest-frame energy band.

^(†)

Sum of the EPIC-pn, EPIC-MOS1 and EPIC-MOS2 net counts in the 0.3–7 keV energy range.

^(⋆)

Chandra total net counts in the 0.5–7 keV energy range.
