Fits of the two 2019 and 2020 simultaneous XMM-Newton/pn and NuSTAR spectra with the RELXILL relativistic reflection model that assumes a coronal geometry for the disc emissivity. Black: 2019 XMM-Newton/pn; dark grey: 2019 NuSTAR; blue: 2020 XMM-Newton/pn; light blue: 2020 NuSTAR. Top panel: fit above 3 keV, which has been extrapolated down to 0.3 keV. The fit parameters are reported in Table 2. Bottom panel: fit over the full 0.3−79 keV energy range. The fit parameters are reported in Table A.1.
