I wont be able to make today's material meeting. I have attached some histograms of the total momentum for run 8468. The plots are:

Ptot_US_track - total momentum of the muon calculated from the square root of the sum of the squares of the Cartesian components read from the root file for the track in the Upstream Tracker.

Ptot_US - total momentum after track has been propagated from upstream tracker to absorber.

Ptot_DS - total momentum after track has been propagated from downstream tracker to absorber.

Ptot_DS_track - as Ptot_US_track, but for the downstream tracker.

I'm still trying to understand what is happening.
