19Geometry of the trigger chambers : a vertical gap of has been introduced around x=0 according fig.3.27 of the TDR (P.Dupieux)

236fe2c5 21Revision 1.23 2001/01/18 15:23:49 egangler
22Bug correction in StepManager :
23Now the systematic offset with angle is cured

a7e8b51a 28Revision 1.21 2000/12/20 13:00:22 egangler

30Added charge correlation between cathods.
31In Config_slat.C, use
32 MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of
33 q1/q2 to 11 % (number from Alberto)
34 This is stored in AliMUONChamber fChargeCorrel member.
35 At generation time, when a tracks enters the volume,
36 AliMUONv1::StepManager calls
37 AliMUONChamber::ChargeCorrelationInit() to set the current value of
38 fCurrentCorrel which is then used at Disintegration level to scale
39 appropriately the PadHit charges.

99(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
100to allow development of slat-muon chamber simulation and reconstruction code in the MUON
101framework. The changes should have no side effects (mostly dummy arguments).
102(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
103of chambers with overlapping modules (MakePadHits, Disintegration).
