DM-42747: Fiducial values for summary stats for comCamSim

[kadrlica]

Adds fiducial values of seeing, sky brightness, and zeropoints for comCamSim in preparation for processing of Ops Rehearsal 3. Note: fiducials are not set for the characterizeImage task, since there is no comCamSim-specific config for this task.

...is not a reason to skip adding a needed config override (i.e. you would need to add the file). But in this case, this:

is a good reason not to include it 😉

[kadrlica]

Yeah, that is a much better reason :).

Here is the successful Jenkins run 972.

This looks fine to me. Just a minor thing...I suggest you expand a little on the "Plots can be found in DM-42747" comment. Perhaps "Plots, including the median values used here, can be found on JIRA ticket DM-42747"? It'll need a rebase before merging as well.

Happy to sign-off on this - no need to re-request.
