Scatter plot of the Ml 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 found by our reconstruction. Both quantities are shown on a logarithmic scale. 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 two maps on log-log scale, ρ.
