New Calibration
Single electrons and photon events
E = 0 - 11 GeV
A calibration curve for each of the 332 crystals
Procedure: if in bank ”MC::Particle” the electron/photon is present,
the algorithm acquires from bank ”FTCAL::clusters” the information
concerning the generated and reconstructed energies and associates it
to the crystal identified by the bank (the bank gives the ”x” and ”x”
position of the cluster).
Fitting function
f (x) = c0 + c1 · x + c2 · x
