So, here is my proposal here: a simple parametric dataset based on CFIS-like conditions:
I've implemented a first prototype of this in #40, with an option to include a shear of 0.02 or not.
Looks like this:
@aguinot does that look good to you? As a toy reference galaxy sample? We of course have only 80000 cosmos galaxies but we can augment them as much as we want with random rotations/reflections + different noise realisations.
I think this is reasonable. We may want to cut some galaxies at mag > 24.5 since there are going to be dominated by noise. Regarding the sample size I am not too worry at the moment, I don't see the need for a larger sample given our current experiment. We can think more about that later. Do you have some images of those galaxies to see what they look like?
This issue is to track the definition of a fairly realistic galaxy sample we may wish to use for testing. Choices made here are being implemented in #34
