Step 4: FWHM conservation test on galaxies. On the x-axis we plot the FWHM of the objects measured on Noiseless image FWHMnoiseless, whereas on the y-axis we plot the FWHM measured on the original image after the application of the denoising algorithms FWHMdenoised. μ and σ are the mean and the standard deviation of the distribution of FWHMdenoised − FWHMnoiseless.
