| 49 | Added charge correlation between cathods. |
| 50 | In Config_slat.C, use |
| 51 | MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of |
| 52 | q1/q2 to 11 % (number from Alberto) |
| 53 | This is stored in AliMUONChamber fChargeCorrel member. |
| 54 | At generation time, when a tracks enters the volume, |
| 55 | AliMUONv1::StepManager calls |
| 56 | AliMUONChamber::ChargeCorrelationInit() to set the current value of |
| 57 | fCurrentCorrel which is then used at Disintegration level to scale |
| 58 | appropriately the PadHit charges. |
