Hi Mason,
Very interesting results. Let's discuss them at our EMCAL meeting this Friday.

Cheers,
Craig

Dear all,

It's Mason from the UIUC sPHENIX team. Attached are some slides that I made while looking into odd single pixel gap behavior in sector 17 (across multiple runs).

The synopsis is that we see distinctly different single pixel gaps between IBs 0-2 vs IBs 3-5 in sector 17. Taking a look at the fits, we see that this is likely due to higher noise levels in IBs 0-2, which the fitting algorithm struggles with.

We plan to investigate if we see similar behavior in other sectors. If the fits do not accurately represent the data, we may also look into developing a fitting algorithm that better handles higher noise levels like those we see in sector 17 IBs 0-2.

Best regards,
