Feature request: pixel-based matching & multi-extension opening #164

Open keflavich opened 1 year ago

keflavich commented 1 year ago

I'm starting to work with JWST data in CARTA, and they are not well-supported.

JWST data have multiple extensions that are all the same image size - they are the image, the error map, and various flag and weight maps. The extensions past the first do not have WCS attached. These cannot (afaict) be match using CARTA's positional matching. Pixel-based position matching should be supported.

I'd also like to be able to open multiple extensions at the same time, perhaps as a cube.

We support channel-based spectral matching, so it makes sense to enable this for spatial matching as well :+1:

Could you open a separate issue for this?

Shouldn’t be this another compatibility issue that probably we can extend wcs to other extensions internally?
