Illustration of our pre-processing pipeline on a random COSMOS image, and the difference between HST and Euclid. The original image (leftmost) is rotated to be aligned with the x-axis of the stamp in the second image from the left, then re-scaled to the VIS resolution and cropped (third image from the left). This is the data used to train our model. In the rightmost image the galaxy was deconvolved by the HST PSF and re-convolved with the Euclid PSF. This final step is shown for illustrative purposes, but is not carried out in the pre-processing of the training sample.
