Notes. The corresponding statistics are also shown. The cross-correlation constants used for XMM-Newton and the FPMA&B data are always within a 10%. The L39 quantity refers to the luminosity in units of 1039 erg s−1, and D10 is the distance in units of 10 kpc, as defined in the XSPEC manual (see https://heasarc.gsfc.nasa.gov/xanadu/xspec/manual/node137.html).
