-
-Revision 1.21 2000/12/20 13:00:22 egangler
-
-Added charge correlation between cathods.
-In Config_slat.C, use
- MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of
- q1/q2 to 11 % (number from Alberto)
- This is stored in AliMUONChamber fChargeCorrel member.
- At generation time, when a tracks enters the volume,
- AliMUONv1::StepManager calls
- AliMUONChamber::ChargeCorrelationInit() to set the current value of
- fCurrentCorrel which is then used at Disintegration level to scale
- appropriately the PadHit charges.
-

--> some useless includes removed or replaced by "class" statement
-
-Revision 1.5 2000/06/28 15:16:35 morsch
-(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
-to allow development of slat-muon chamber simulation and reconstruction code in the MUON
-framework. The changes should have no side effects (mostly dummy arguments).
-(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
