Agenda

1. • 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.
