  • Used bpmAllLog_20101215_083831.dat (24 hours later) for the SVD, only 100 pulses
  • In Y the jitter is small, so the calibrations without subtraction agree very well, while subtraction does not remove the jitter, so the subtracted calibrations are WORSE
  • In X the scales are much more stable. The IQ rotation is less stable due to uncorrected angular jitter
  • Need to try this again with more up-to-date data used for the SVD, and with 200-300 pulses, before can draw any final conclusions
