Agenda
- Cameron, Question about BCM pedestals - BCM linearity studies updatePedestal studies update
- CP: different ways to estimate unser pedestal error bar.
- KP: it would be useful to have chi-square distribution from each fitting
- KP: data points speard around one percent.
- CP: should we use constant pedestal or moving pedestal for entire run?
- KP: have we ever changed PMT HV ? Devi: No.
- KP: we can use constant pedestal.
- PK: calibrate analog us bcm first and calibrate others against it to get pedestals.
- Devi: AT update[HAPLOG 4082]
- Devi: Could it be inelastic contribution?
- KK: carbon asymmetry should be dominant here
- KP: inelastic asymmetry should have same sign and similar amplitude.
- KP: you can project tracks from focal plane and see if there is pole-tip.
- KP: you can show residual correlation with BPMs next week.
- PK: summary of respin2 changes next week.
