There was a problem hiding this comment.
Could you avoid using TVector3? While it is convenient, all those extra allocations will be considerably slow, if this dynamic column is called within a loop. It would be better to use plain calculation and add common parts as functions to RecoDecay header.

The latest commit gets rid of the TVector dependency... should be good to go now! Thanks again to @dsekihat :-D |
