jFEX Jet calibration back - only eta dependent

Sergi Rodriguez Bosca requested to merge serodrig/athena:Update_JetEtCalib into 23.0

This MR is meant to put back the jFEX jet calibration. This time it is not Et-dependent, just eta-dependent. Values used here are shown in the TDAQ (slides here) Those parameters are still under study so there are some commented lines that we should leave there until a final decision - soon i hope. Calibration factors are:

  • jFEX 3A/C = 1.66666667 - Most central FPGAs (abs. eta 0.0 - 0.8)
  • jFEX 2A/C = 1.97160883 - Middle FPGAs (abs. eta 0.8 - 1.6)
  • jFEX 1A/C = 1.65343915 - Forward FPGAs (abs. eta 1.6 - 4.9)

Rates/Counts in jJ items are expected to increase. You should notice that this is not what the hardware is doing nowadays, therefore we cannot make a 1 to 1 comparison.

Tagging @tamartin, @hillier and @cantel for further studies and x-checks
