Task #746: PID threshold optimization on HMS
Added by Alexandre Camsonne 8 months ago. Updated 6 months ago.
Hi Zheng, could you look at all the run ps3=0 and plots the efficiencies as function of run number. Hopefully they are all high and not changing much.

Hi Alex, I finished the code on reading the HMS trigger efficiency from the hcana report output but it is only about the hodo 3/4 but I am wondering if we could also get the elreal trigger efficiency from those ps3=0 runs as well. I read some previous thesis from hallc (but slightly different elreal setup) and got a brief idea on how to calculate them. Maybe let me give a try first and we can discuss it during the analysis meeting tomorrow.
