Quiescent pn spectrum of RX J1301.9+2747 during the 2020 epoch, visually rebinned to 3σ significance and overplotted to the posterior PDF of model 0 ([diskbb], top panel), model 1 ([diskbb + bbody], middle panel), and model 4 ([diskbb + compTT], lower panel). The [diskbb] component is plotted in red, the [bbody] in orange, the [compTT] in brown, and the total model in gray. The complete set of spectra for all epochs compared to models 0 and 1 are shown in Fig. C.2. Spectra are shown up to 2 keV, as at higher energies the signal is dominated by the background, however the data were always fitted up to 10 keV.
