18 // FUNCTIONALITY:
19 //
20 // 1. The laser track is associated with the mirror
21 // see function FindMirror
22 //
23 // 2. The laser track is accepted for the analysis under certain condition
24 // (see function Accpet laser)
263d466a 25 //
2b35e8e6 26 // 3. The drift velocity and jitter is calculated event by event
263d466a 27 // (see function drift velocity)
2b35e8e6 28 //
be113f6e 29 // 4. The tracks are refitted at different sectors
30 // Fit model
31 // 4.a) line
32 // 4.b) parabola
33 // 4.c) parabola with common P2 for inner and outer
2b35e8e6 34 //
