Energy spectrum of the Hoinga SNR as observed with the eROSITA TM1, 2, 3, 4, and 6 telescope and detector units and simultaneously fitted to an absorbed APEC spectral model (upper panel). The spectra have been binned for visual clarity and plotting purposes. The signal-to-noise ratio in each bin is 15σ. The folded best-fit APEC spectral model is plotted as a solid black line. Fit residuals are shown in the lower panel.
