I am developing an obs package to process VISTA VIRCAM imaging. I would like to produce joint HSC-VISTA catalogues and eventually LSST-VISTA by warping the images to the same sky map and merging the detection catalogues as is done for HSC bands in the pipelines examples. I am currently working on the VISTA only part as a test.
My question is would I need to, and is it possible to, use two obs packages simultaneously. Can I for instance import HSC images to the same Butler repository as my VISTA images using the obs_subaru package alongside my new obs_vista package? The command line tasks seem to assume the Butler repository is for one instrument but I wonder if I delve into the code directly I can use two.
Many thanks for any help or interest.
