[Tpe] tof calibration trends

[Puneet Khetarpal]

Hi All,

I've made a plot of the delta t (reconstructed - calculated) for pions
and protons as a function of run number for the files that have
already been cooked (negative torus polarity). Overall things are
stabler than I thought. Some runs haven't been cooked properly (See
note in the link). Proton's calibration is worse than pions as
expected because of slower momentum, worse resolution, fewer
statistics, and background contamination in the fit. But hopefully
things should improve with additional rf offset calibration. Things
are also drifting as usual. But now I know which runs to calibrate.
Would like to see how this changes with positive torus polarity.
