  1. Track Resolution Scale , assume equal smeas for different planes. All 6 measurements. Without leftmost one. Without rightmost one. HP3 HP4 JC Wang

  2. Recovery of JC Effect Events: 231, 232, 233 M28R • Pedestal shift in the whole chip  -0.12 Q(in unit of MIPs). • Normal CM suppression can not handle large shift. • Hottest events removed from running pedestal calculation. • Extra correction to recover hits in the rest of the chip. Raw ADC Readout Chip 5 Signal after Extra Correction ADC – Pedestal – CM noise ~ 50 ADC Electronic Channel Electronic Channel JC Wang

  3. Pedestal & CMS Noise Before After JC Wang
