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.
