Two examples of reconstructed images using the pseudo-Zernike moments. For each panel (made up of six subpanels): top left: observations; top center: reconstructed image using m up to 12; top right: residuals of the modeling; bottom left: reconstruction of the image using only m = 0, related to radial and uniform azimuthal distribution; bottom center: reconstruction of the image using |m| = 1 and 2, corresponding to the adopted inhomogeneous contribution; bottom right: reconstruction of the image using 1 ≤ |m| ≤ 12, related to all the azimuthal contributions. For each subpanel the color scale is the same.
