The STAR experiment

This is a follow-up of my previous blog post, making use of the jobs I ran for it: Compare event-by-event T0 performance.

Using a file from the Run 19 FXT dataset production_4p59GeV_fixedTarget_2019, which I previously calibrated for event-by-event T0s, I examined the performance of three
