Table 1
Best fit parameters of the variable component of the emission observed in the eFEDS field, once the difference spectrum (e3 minus e1) is fitted with the acx2 model.

Notes. The first column (kTSWCX) lists the plasma temperature, in units of keV. The second column (FHe0) is the fraction of neutral helium (relative to the total neutral population, assumed to be H and He) in the plasma. The third column is the flux of the acx2 component in the 0.4–0.6 keV band, over the eFEDS region, in units of 10−13 erg cm−2 s−1 deg−2. Columns 5 and 6 give the χ2 and the degrees of freedom.
