This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
* initial commit. * move ProducerTBout.cc from test to plugins * KFin fully debugged. * Producer TBout added to NTupleMaker * chriss change to KFout * Louises first comments. * fixing rebase errors. * KF reintegrated, stub residuals are not bit accurate yet. * code format. * added 1k ttbar@0PU events for internal kf maths tuning. * Track builder r residual debug and KF digi function corrected. * bug in z residual base fixed. * Ians first comments. * Ians secodn comments. * recalculate z ressid from TTStubRefs, use TTStubRefs for seed stubs instead of fake stubs. * Ians third comment. * fixed comments TTDTC::Frames -> tt::Frames * old stub uncertainty caclulation re-enabled. * Ians 4th comments. * code-checks. * tilted stub z uncertainty fixed. not yet debugged against f/w. * set max layers a kff adds to a track to 7 as we did in the past, no clue why it is 4 again ... * agrrement with f/w, ready to merge.
