Rate comparison of diffuse emission maps of eROSITA/eRASSl and ROSAT/RASS in log scale. Each data point shows the rates from 0.83 deg² sky region (NSIDE 64). The converted eROSITA rates were calculated from Eq. (2) to be equivalent to the ROSAT response. The screening is by S/N > 3 in the ROSAT data. The color corresponds the density of the data in this plot. The navy points with error bars mark the density peak in the eROSITA rates with a 1σ confidence. The navy dash-dotted line is the best fit of the densest points. The lines with a slope of 1 and 0.75 (1.25) and zero intercept are shown with the solid red line and dashed black lines, respectively. The intrinsic Poisson uncertainty level corresponding to 1 pix size is shown by the gray shadow.
