Methods Documentation

add_catalog_members()

Add catalog and direct image member based on direct image members

finalize()

Finalize the association

For WFSS, this involves taking all the direct image exposures, determine which one is first after last science exposure, and creating the catalog name from that image.

get_exposure_type(item, default='science')

Modify exposure type depending on dither pointing index

If an imaging exposure as been found, treat is as a direct image.
