Hi Abhisek,

I talked to John L, John H, and Jin and we’d like to show the e / pi ratio without the simulation on Tuesday. Can you update the plot?

Best,

Anne

Hello HCALers,
Anne's IEEE talk is next week. So I have added "sPHENIX preliminary" label to HCAL plots for everyone to review. Please let me know if you have comments.

HCAL Standalone plots:

Please refer to testbeam paper for analysis details. Few comments:

1/ The nonlinearity observed in HCAL is a preamp saturation effect. A suggestion during the HCAL workfest was to remove the saturation points and rerun the analysis to improve the linearity. We made a new production but results were same. I think the fitting changes were not included. Jin is looking more into it. We will likely have one more new production.

2/ I intentionally did not add e/pi plot for sPHENIX configuration. That needs more internal discussion.

Please let me know if you have any comments.

Cheers,

Abhisek
