In rfquad/20240104_170525 - 150k muons, scraping and rf quad
   rfquad/20240105_170554  - RF quad off

  Those two above are pretty indistinguishable when plotting moments from Time_Dep_Moments_at_END.dat
  Try flipping sign of horizontal rf amplitude
      20240105_125043
   or doubling the horizontal rf amplitude

  Unable to distinguish effect of rf in stored distributions from Time_Dep_Moments_at_END.dat
  Check out effect on single particle.

  Set starting point at inflector exit with offset 77mm

20240125_12310 out1.dat Having discovered in 20240124_102811 scan starting at rf amplitude of -10 that that
 is the minimium cbo, start another scan from -15. -10.
   Sure enough -10. gives min cbo

Also find minimum in phase scan 20240124_092058 at 153 deg, consider returning there after amp is optimized. 

January 26, 2024
Find a mistake in that phase for q2 is 110 rather than 90 deg from Q1. This in min cbo case.
Set RF as
