Notes. The top panel lists the best-fit parameters of the background model and the bottom panel shows the parameters of the source models (details are in Sect. 3.1.2). Errors are given at the 90% confidence level. We required the emission measures of the vpshock and vsedov models to be in the 99% CL range of EM obtained with the vapec model (see Sect. 3.1.3), and this gave us the range of errors for kT and τ of the vpshock and vsedov models. The χ2 and associated degrees of freedom (d.o.f.) are also listed.
