Scatter plot of the M2 diffuse flux density values in the 1.00-1.77 GeV energy bin against the Planck 545 GHz thermal dust emission map values. Each pixel is represented by a dot, with the x-axis showing the brightness temperature measured by Planck for this pixel and the y-axis showing the corresponding flux density value of our reconstruction. Both axes have a logarithmic scale. The points for the dust template informed diffuse component I^dust are shown in orange, while the points for the a priori dust-independent diffuse component I^nd are shown in purple. The text in the upper left corner shows the slope of a linear fit to the dots, α, and the Pearson correlation coefficient between the thermal dust map and our reconstructions on log-log scale, ρ.
