25Dependency on implementations of AliSegmentation and AliMUONResponse moved to AliMUONFactory class.
26Static method Build() builds the MUON system out of chambers, segmentation and response.

46Added charge correlation between cathods.
47In Config_slat.C, use
48 MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of
49 q1/q2 to 11 % (number from Alberto)
50 This is stored in AliMUONChamber fChargeCorrel member.
51 At generation time, when a tracks enters the volume,
52 AliMUONv1::StepManager calls
53 AliMUONChamber::ChargeCorrelationInit() to set the current value of
54 fCurrentCorrel which is then used at Disintegration level to scale
55 appropriately the PadHit charges.
56
681d067b 57Revision 1.20 2000/12/04 17:48:23 gosset

115(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
116to allow development of slat-muon chamber simulation and reconstruction code in the MUON
117framework. The changes should have no side effects (mostly dummy arguments).
118(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
119of chambers with overlapping modules (MakePadHits, Disintegration).
