20Added charge correlation between cathods.
21In Config_slat.C, use
22 MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of
23 q1/q2 to 11 % (number from Alberto)
24 This is stored in AliMUONChamber fChargeCorrel member.
25 At generation time, when a tracks enters the volume,
26 AliMUONv1::StepManager calls
27 AliMUONChamber::ChargeCorrelationInit() to set the current value of
28 fCurrentCorrel which is then used at Disintegration level to scale
29 appropriately the PadHit charges.

681d067b 31Revision 1.20 2000/12/04 17:48:23 gosset
32Modifications for stations 1 et 2 mainly:
33* station 1 with 4 mm gas gap and smaller cathode segmentation...
34* stations 1 and 2 with "grey" frame crosses
35* mean noise at 1.5 ADC channel
36* Ar-CO2 gas (80%+20%)

89(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
90to allow development of slat-muon chamber simulation and reconstruction code in the MUON
91framework. The changes should have no side effects (mostly dummy arguments).
92(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
93of chambers with overlapping modules (MakePadHits, Disintegration).
