Preparing for respin2

Pedestal updates
- Use beam off for non-RF systems
- Verify segmentation and values for RF systems
- Refer to beam off pedestals for guidance on applicability ranges
- Double check PITA scans from respin1 data and BPM calibrations separately
Aq shift - solved

Preparing for respin2

Pedestals/new beam trip cut/Aq interrelation question
- Aq post-trip studies: http://ace.phys.virginia.edu/HAPPEX/4483
  - Things look good when comparing the different time slices post-trip recovery - more plots are needed to determine how well the non-feedback data post-trip explains the shift in Aq from prompt to respin1 data set.
- Pedestal comparisons for AT: http://ace.phys.virginia.edu/HAPPEX/4482
  - Changing from prompt (wrong) to respin1 (relative to bcm calibrated) pedestals changed the mean asyms by an expected ~3% per target, EXCEPT for Pb208, which changed by ~15%. This needs further investigation to understand why Pb pedestal change affected the asyms so much.
