Notes. The XSPEC models zbbody and zpowerlw are in the rest frame (z = 0.020598). ^(a)Source counts over 0.4–10 keV for XMM-Newton and over 0.4–8 keV for Chandra. ^(b)Multi-temperature disk blackbody normalization defined as f⁻⁴(R_in/D₁₀)²cos i, where R_in is the inner radius (unit in km) of the disk, D₁₀ the distance to the source in units of 10 kpc, f the spectral hardening factor, and i the inclination of the disk. ^(c)Blackbody normalization defined as L₃₉/D₁₀², where L₃₉ is the source luminosity (10³⁹ erg s⁻¹), and D₁₀ the source distance (10 kpc). ^(d)The unabsorbed X-ray flux and luminosity (D = 82 Mpc) over the 0.4–8 keV energy band.
