TrChecker

This is the code that generates histograms that detail the performance of the tracking algorithms. It by default monitors the Best tracks which are the tracks that have been found by any algorithm after the clone killer has removed tracks that appear to be from the same MC particle.

By default there is a root file generated by Brunel, along with the DST file, that has the default monitoring histograms. The tracking histograms include:

Histogram
1 Number of tracks per event
2 Number of true tracks per event
10 Error flag
11 Unique flag
12 Track Type
20 Track efficiency per event
21 Track ghost rate per event
30 Momentum (GeV) first state
33 True momentum (GeV) for MCParticles
40 Hit purity
41 Velo hit purity
42 IT hit purity
43 OT hit purity
50 Hit efficiency
51 Velo hit efficiency
52 IT hit efficiency
53 OT hit efficiency

Also the resoltions and pulls in x, y, dx/dz, dy/dz and q/p at the production vertex, first measurement and 5 other z values are plotted.
