X-ray spectra of the targets. The plasma emission models are depicted by the histograms and the source count rates by diamonds with error bars. The χ² contours for the 1, 2, and 3σ confidence intervals of the model parameters are shown in the inserts. WASP-80 was fitted with a two temperature model; the contours of the four parameters are not shown. With the exception of WASP-10, which only has five source counts, the model parameters are well confined.
