Dear All,
I'm trying to analize the following channel:
psi(4040) -> D*+ D*- -> D0 D0bar pi+ pi-
with the neutral mesons going to k pi pi.
I have some problem with the 4 constraint fit, you can find the all the macro in the attachment.
I got the following error, already with the first event:

loop index 0
0
Error: illegal pointer to class object dstarpu 0x0 4521 ana_4constraint.C:251:
*** Interpreter error recovered ***


I was also trying to access the TCandidate of the fitter, but I got the same error.
Does anybody of you know how to solve this problem?
Thanks in advance,
Best Regards,
Laura

Ciao Laura,

My first suggestion would be that you join the people who try out the brand new changes to the RHO package. There I repaired many things with accessing the fitted objects.

Cheers
Ralf
