Add track incident angles
Goal of this MR:
Implement histograms that show the track incident angle on each plane.
Currently, we only have a histogram for the track angle in the global reference frame (and only for straight-line, this makes no sense for GBL) and the kink angles at each plane for GBL.
Approach:
First, I thought it would be better to implement a new function getIncidentAngle() as part of the Track class:
track->getIncidentAngle(detector);Started implementing that in:
- a493678a (reverted in edb88aa3)
- e1837430 (reverted in bfa2c692)
- 76c83f9a (reverted in 7246c8b3)
- b0b67aab (reverted in 085dd694)
But then I saw that the Track class doesn't know detector but only has the concepts of planes. And I need detector->rotation() to get the orientation angles.
In turn, the Detector class already knows track, so it fits in more naturally like this:
detector->getIncidentAngle(track);Please have a look at the current implementation and let me know what you think. Of coarse, some clean-up and testing is still necessary.
