Notes. The absorbed thermal model has the form phabs(ISM) × phabs × apec with $N_{H}^{I S M} = 2.7 \times 10^{20} {c m}^{- 2}$ $\[N_{\mathrm{H}}^{\mathrm{ISM}}=2.7 \times 10^{20} \mathrm{~cm}^{-2}\]$ and kT = 9.1 keV. Fluxes are provided in units 10⁻¹¹ erg cm⁻² s⁻¹. For individual eROSITA spectra, the errors on absorbing column and normalization factors were very asymmetric, hence the 1σ confidence interval is provided instead.
