Rogers:- Should require 5 space points per tracker on the PRStraightTrack
- Should require 15 track points per tracker
- Add TKU radial plot
- Note first slide - dependence between TOF0/TOF1 triggers is inverted
- Second slide - lots of worry about statistical noise; hysteresis? beamline stability?
- Check the reference runs for consistency
- Check the alarm handler settings - where is the alarm limit for the conventional magnets; are CDB set values consistent with alarm limit
- Still see big spike at the M2D coil
- Remove M2D
- Remove trackers
Note that it is consistent with z position of transmission loss; nonetheless not improved
