Notes. The X-ray luminosities of the plasma emission components are computed in the 0.3 − 10 keV energy range, assuming a distance of 4.5 Mpc. ^(a)indicates that the parameter is pegged at the lower boundary of the allowed range. ^(b)indicates coupled parameters: for each dataset, kT_bb = kT_{in, comt}. The hydrogen column density, N_H, of the interstellar medium is fixed at 5.4 × 10²⁰ cm⁻², as obtained for the time-averaged data.
