Multi-band Image Generation #61

Open P-1884 opened 1 month ago

P-1884 commented 1 month ago

PR to generate multi-band imaging, made during DESC 2024 Sprint Day, as a precursor to training on multi-band imaging. Main features:

Chosen parameters can be drawn from filter-dependent distributions (e.g. lens magnitudes drawn from different distribution depending on band).
All parameters are fixed to be the same across bands (e.g. Einstein radius shouldn't change).

Current shortcomings:

Though the parameters are drawn from different distributions, the draws from a given system are not correlated.
The code is currently (very much!) in draft stage and has not yet been properly bug checked (e.g. seeding between bands needs fixing)
