Tracking in FOOT sections

In FOOT, tracking is performed separately for each section

Tracking in each section

Tracking parameters for each sections are stored in track_Sx.rootrc . They need to be copied before launching track reconstruction, as written in tracking_stacks.sh

We usually perform tracking with realignment:

• Before we launch tracking with alignment (in track.rootrc modify variable: fedra.track.do_realign 1)

• Without launching makescanset again, launch tracking standard (in track.rootrc modify variable: fedra.track.do_realign 0)

We obtain track files b00000*.*.0.0.trk.root, one for each section (S1, S2,S3...S7)

Merge trackings

• prepare scanset for whole brick: BRICK.0.0.0

• root -l launch_mergetrackings2.C
