Scanamorphos (left) and PhotProject (right) images of IC 10 at 70 μm to illustrate how PhotProject tends to clip out the extended features. The colours and spatial scales are the same on both images. Here the diffuse extended emission is best visible on the Scanamorphos map. The comparison of the total flux densities coming from the 2 methods confirms that PhotProject misses the extended emission: in this case, F70(Scanamorphos)/F70(PhotProject) = 1.5.
