Dear All,
after the last modification of the PndChiVtxFitter.cxx
these are the main results that I got.
Resolution on x: 32 micron
index.php?t=getfile&id=7460&private=0

Resolution on y: 54 micron, why is it different from x?
index.php?t=getfile&id=7462&private=0

Resolution on z: 113 micron.
index.php?t=getfile&id=7461&private=0

Chi2 still some negative values: do you have suggestions on how to decide what is the best candidate in case of combinatorials?
index.php?t=getfile&id=7463&private=0

Mass of the D0 before and after the fit: after the fit we got a low number of D0 under the central peak
index.php?t=getfile&id=7464&private=0

Best regards,
Laura
