Ca: patch to the RC2
MR should fix the issue https://redmine.cbm.gsi.de/issues/3149
It contains the following fixes to the CA tracking:
-
bugfix in the Jacobian of the track extrapolation. (It was introduced during the rewrite of the math)
-
tune binning of the hit grid. (A little decrease of the efficiency happened after the code rewrite)
-
tune the cuts for newly introduced hit ranges. (The new formulae were not tuned)
-
revert triplet cut on space + time chi2. (After the split of space and time Chi2 in the track fit, the chi2 cut was changed w/o tuning. Replace it with the old cut.)
@f.uhlig, please put the MR to the release.
