Comparison between the luminosity measured with eROSITA and the luminosity reported in Maggi et al. (2016) based on data from XMM-Newton in the energy range 0.3–8.0 keV. The shaded region shows the 95% confidence interval around the best-fit line. The dashed line shows the 95% prediction interval. The bottom panel shows the residuals between the data and the best fit. From the plot, the agreement between the luminosities of SNRs obtained by the two different instruments is evident.
