Notes. The fit model and the physical parameters correspond to those discussed in Sect. 3.2.2. The horizontal line separates the two groups of spectra shown in separate plots in Fig. 4. We show constraints on the column density N_H, mean plasma temperature kT_mean, electron density ${\bar{n}}_{e}^{tot}$ $\bar{n}_{e}^{\text {tot}}$ , energy ϵ, pressure P_tot, elemental abundances, as well as on nonthermal spectral index Γ and intensity Σ_Γ. ^(a)For this region, we give the parameters, including the ionization age τ_hot, for the NEI model vpshock (Borkowski et al. 2001) in the hot component, which was strongly statistically preferred. ^(b)For all regions, a Gaussian prior with mean 2.0 and width 0.5 was applied to Γ.
