Update Euclid-like PSF normalization to remove obscuration #86

Closed FedericoBerlfein closed 1 month ago

FedericoBerlfein commented 1 month ago

PSF images provided are normalized for obscuration, vignetting and baffle effects. However, GalSim internally handles the obscuration, so we remove this part of the normalization by dividing the PSF images by collecting_area / ((diameter/2)**2*np.pi).

New test is exactly what I had in mind, thanks.
