34 | Revision 1.21 2000/12/20 13:00:22 egangler |
| 35 | |
| 36 | Added charge correlation between cathods. |
| 37 | In Config_slat.C, use |
| 38 | MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of |
| 39 | q1/q2 to 11 % (number from Alberto) |
| 40 | This is stored in AliMUONChamber fChargeCorrel member. |
| 41 | At generation time, when a tracks enters the volume, |
| 42 | AliMUONv1::StepManager calls |
| 43 | AliMUONChamber::ChargeCorrelationInit() to set the current value of |
| 44 | fCurrentCorrel which is then used at Disintegration level to scale |
| 45 | appropriately the PadHit charges. |
