+Revision 1.28 2001/05/16 14:57:17 alibrary
+New files for folders and Stack
+
+Revision 1.27 2001/04/06 11:24:43 morsch
+Dependency on implementations of AliSegmentation and AliMUONResponse moved to AliMUONFactory class.
+Static method Build() builds the MUON system out of chambers, segmentation and response.
+
+Revision 1.26 2001/03/17 10:07:20 morsch
+Correct inconsistent variable name / method name / comments.
+
+Revision 1.25 2001/03/16 15:32:06 morsch
+Corrections of overlap with beam shield and dipole (A. de Falco)
+
+Revision 1.24 2001/03/14 17:22:15 pcrochet
+Geometry of the trigger chambers : a vertical gap of has been introduced around x=0 according fig.3.27 of the TDR (P.Dupieux)
+
+Revision 1.23 2001/01/18 15:23:49 egangler
+Bug correction in StepManager :
+Now the systematic offset with angle is cured
+
+Revision 1.22 2001/01/17 21:01:21 hristov
+Unused variable removed
+
+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.
+
+Revision 1.20 2000/12/04 17:48:23 gosset
+Modifications for stations 1 et 2 mainly:
+* station 1 with 4 mm gas gap and smaller cathode segmentation...
+* stations 1 and 2 with "grey" frame crosses
+* mean noise at 1.5 ADC channel
+* Ar-CO2 gas (80%+20%)
+
+Revision 1.19 2000/12/02 17:15:46 morsch
+Correction of dead zones in inner regions of stations 3-5
+Correction of length of slats 3 and 9 of station 4.
+
+Revision 1.17 2000/11/24 12:57:10 morsch
+New version of geometry for stations 3-5 "Slats" (A. de Falco)
+ - sensitive region at station 3 inner radius
+ - improved volume tree structure
+
+Revision 1.16 2000/11/08 13:01:40 morsch
+Chamber half-planes of stations 3-5 at different z-positions.
+
Revision 1.15 2000/11/06 11:39:02 morsch
Bug in StepManager() corrected.
