Hi Stefano,
I just looked into the PidCorrelator code and found some reasons for -1:

* no MC or no MCindex found when ideal pid is used
* cluster energy below emc barrel threshold 20 MeV
* hit not come from emc or fsc
* no propagation at module when geane is used

** too low momenta (< 0.1) or too high momenta (> 15) // ?? why 0.1 GeV/c
** track flag <= 0
** no track info

And the "nearby" criteria of emcquality < 2500 is distinguishing the neutral candidate and the track-correlated hit. Then, the track-correlated hit will be constructed as a charged candidate.
Do I understand it right?

Best regards,
Lu
