First and second columns: XMM-Newton/pn and NuSTAR (in red) spectra of T CrB taken during the SAS. The model parameters, listed in Table A.1, were obtained by simultaneously fitting the pn, MOS 1 and MOS 2 spectra during each pointing. Here we show only the pn spectra for clarity. Third column: NuSTAR/FPMA, XMM-Newton, and Swift spectra of T CrB taken during the faint state after the SAS. The Swift spectra were grouped at one count per bin and modeled using Cash statistic.
