Dear analysis experts,
I run the standard macro/run/ana_complete.C macro and checked the chi2 distributions of the three fitters implemented there, vertex mass and 4C.
Here the plots:

You can see that the vertex fitters shows still negative values of chi2. I supposed this was fixed. Did I forget something, or maybe there is still something to debug?
