Remove blank space when simulating individual CCDs #14

Closed bojobo closed 4 months ago

The focal point of EPN is not in the center because of the gaps between the CCDs. It is rather shifted a bit. This shift results in empty rows and columns on the upper and right edge. Remove these to reduce the size of the image.

Also, while at it: Make sure that pixel values are first multiplied with res_mult and afterwards rounded up with np.ceil when calculating them.

While testing, I've noticed that the shift done by this line is wrong. I'm not quite sure how these values have to be used.

Got it: The shift should be used to center the image.
