[Clas12_calcom] [EXTERNAL] Re: new timelines for RGC-summer22

[Raffaella De Vita]

Dear Silvia,

Here is an update on FTCal:

- for the empty target runs, the timeline is actually misleading because the assumption on the FT photons vertex to be at the center of the target cell is not accurate and the pi0 mass comes out shifted even is the energy calibration is good. For example, runs 16184-16194 are in the middle of a run range sharing the same constants where production runs before and after are within specs.
- runs 16271-16279 and 16296-16403 are after the high luminosity irradiations and the calorimeter response varies too much from run to run and probably within the runs to do much about it.
- runs 16280-16287 and 16751-16772 should be fixed now: I made a mistake when uploading the constants and the constants were still the old ones from last year.

In summary, I don’t think I need new runs to be cooked and the next timeline should hopefully be good.

Best regards,
	Raffaella
