sigma for fits in ls_dr7?

Question

Does information about the per pixel uncertainty/sigma exists in the data labs? The legacy survey itself has an invvar brick which would be exactly what I need, but an svc search in data labs does not result in anything that is a prodtype that would lead me to an uncertainty.

Answer 1

The image service for LS DR7 contains images where the 'prodtype' is 'wtmap' -- these are the invvar brick files you mentioned.  If you do an image search the result list should contain all the image types at a particular position so it should be possible to get cutouts of the pixel data as well as the invvar brick of the same region.

I never would've guessed that, thank you :)
