Coaddition Pipeline #171

Closed guynir42 closed 8 months ago

guynir42 commented 9 months ago

The coaddition pipeline is similar to the top-level pipeline. It can be initialized from the config file or using overrides from kwargs. It then accepts either a list of images or a time range (with both start and end date optional, we can set reasonable defaults for them) + a filter, section ID and coordinates (or target). If using time range/filter/coordinates it will look for all the images within that range and pull them up to make the coadd.

The pipeline will output a coadded image that has source extraction, PSF extraction, astro/photo calibration all done on it.

It can then be saved either as a combined science image (e.g., nightly/weekly science coadds) or as a reference image.

@rknop this is ready for review.
