Hi Stefano,
Here is the chi2 distribution for D0->gamma gamma mass constraint fit.
(detail plots are in the file at first posting of this title)

index.php?t=getfile&id=7942&private=0
Black histrogram is the all candidates and dashed blue is for the MC truth matched one.
I assume that the chi2 values are normalized some factor.

I will discuss with Dima.

Best wishes,
Donghee
