80Added charge correlation between cathods.
81In Config_slat.C, use
82 MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of
83 q1/q2 to 11 % (number from Alberto)
84 This is stored in AliMUONChamber fChargeCorrel member.
85 At generation time, when a tracks enters the volume,
86 AliMUONv1::StepManager calls
87 AliMUONChamber::ChargeCorrelationInit() to set the current value of
88 fCurrentCorrel which is then used at Disintegration level to scale
89 appropriately the PadHit charges.

681d067b 91Revision 1.20 2000/12/04 17:48:23 gosset

149(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
150to allow development of slat-muon chamber simulation and reconstruction code in the MUON
151framework. The changes should have no side effects (mostly dummy arguments).
152(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
153of chambers with overlapping modules (MakePadHits, Disintegration).
