[Clas12_calcom] RGC F22 timelines with new raster calibration

Dear Silvia,

I have noticed for the HTCC that there is a difference in the timing. 
For the previous timelines, using raster calibration constants from 
CCDB, HTCC timing is in spec and looks how I expected:

However, for the new timelines for RGC F22 using an sqlite file with 
modified raster calibration and beam offsets constants, several runs are 
now out of spec for the timing:

And I know that I did not change anything on my end for the HTCC timing 
for RGC F22. Are other subsystems seeing similar issues?

All the best,

Izzy
