How to query number of sources per detector?

Hi all,

For part of a project I’m currently working on, the number of sources on each detector at each visit is an important metric, as I’m interested in the density of sources per visit. Is this number available anywhere (will it be in the prompt products?), or will I need to query it each time?

Hi @awilson110 ,

I believe the number of sources per detector per visit is not provided as a pre-computed summary statistics in any catalogs, meaning that you need to query it each time. In your query, you can use the COUNT function to get the total number of sources of your interest per visit per visit per detector. Does this answer your question?

Hi @galaxyumi331 ,

That’s perfect, I was just checking. That does answer my question, thank you.
