b2a60966 19// Implementation version v1 of the PHOS particle identifier
7acf6008 20// Particle identification based on the
148b2bba 21// - RCPV: distance from CPV recpoint to EMCA recpoint.
22// - TOF
23// - PCA: Principal Components Analysis..
24// The identified particle has an identification number corresponding
25// to a 9 bits number:
26// -Bit 0 to 2: bit set if RCPV > fCpvEmcDistance (each bit corresponds
27// to a different efficiency-purity point of the photon identification)
28// -Bit 3 to 5: bit set if TOF < fTimeGate (each bit corresponds
29// to a different efficiency-purity point of the photon identification)
30// -Bit 6 to 9: bit set if Principal Components are
31// inside an ellipse defined by fX_center, fY_center, fA, fB, fAngle
32// (each bit corresponds to a different efficiency-purity point of the
33// photon identification)
9fa5f1d0 34// A calibrated energy is calculated. The energy of the reconstructed
35// cluster is corrected with the formula A + B * E + C * E^2, whose parameters
36// where obtained thourgh the study of the reconstructed energy
37// distribution of monoenergetic photons.
