[d2n-analysis-talk] 5pass Momentum stability

[posik at jlab.org]

Hi all,

   With the trigger thresholds changing so much during our 5.89 GeV data
set,in addition to looking at the MWDC drift times and track residuals.
I also took a look at the momentum for our 5.89 GeV target spin = 90
deg. data. I attached a plot of the mean momentum histogram vs
runnumber. I used the momentum variable BB.optics.p_firstorder. The
various colors correspond to various shower threshold changes. The
largest variation in mean momentum is ~ 130 MeV.
