Statistical validation. The PDF and angular power spectra for the LSS, tSZ, and Venus fields (left to right). The first row shows the PDF with a linear y-axis scaling, while the second row shows the same PDF with a logarithmic y-axis. The third row shows the angular power spectra. The target is shown in blue, the generated fields in red, and the Gaussian realisations in yellow. We plotted the mean (solid line) and the standard deviation (shadow envelope) over 50 realisations.
