- get_image(image_id=None, path=None, observation_id=None, band=None, sca=None, base_path=None, dbclient=None)[source]¶
Return a OpenUniverse2024FITSImage based on specifications.
If you specify all of path, observation_id, band, and sca, they must be consistent.
If you just give path, then observation_id, band, and sca will be read from the header.
If you give observation_id, band, and sca, but not path, it will use get_image_path to find the image.
NOTE: in the ou2024 files, “observation_id” is called “pointing” and is an int. In snappl, to match what will come from Roman, we use observation_id, and make it a string (even though it’s composed of characters [0-9], it’s a string in the Roman headers).
