NuSTAR and eROSITA spectra of J085039 from FPMA (teal) and FPMB (peach) fitted with three different models. The folded and unfolded models with individual model components are shown in panels (a) and (b), respectively. The χ²-residuals are shown for (c) Model 1a (M1a), the high-energy cutoff, (d) M1b, the high-energy cut-off including a partial absorber, and (e) M1c, the high-energy cutoff including an ionised absorber.
