70Added charge correlation between cathods.
71In Config_slat.C, use
72 MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of
73 q1/q2 to 11 % (number from Alberto)
74 This is stored in AliMUONChamber fChargeCorrel member.
75 At generation time, when a tracks enters the volume,
76 AliMUONv1::StepManager calls
77 AliMUONChamber::ChargeCorrelationInit() to set the current value of
78 fCurrentCorrel which is then used at Disintegration level to scale
79 appropriately the PadHit charges.

139(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
140to allow development of slat-muon chamber simulation and reconstruction code in the MUON
141framework. The changes should have no side effects (mostly dummy arguments).
142(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
143of chambers with overlapping modules (MakePadHits, Disintegration).
144
802a864d 145Revision 1.4 2000/06/26 14:02:38 morsch
