Meanwhile I have tried to check also, tpc with pion riemann, phi and eta_c peaks with standard pion hypothesis (red) and with ideal hypothesis (blue) in PndPidCorrelator.

K+K- invariant mass

index.php?t=getfile&id=6518&private=0

eta_c invariant mass

index.php?t=getfile&id=6519&private=0

It seems that the ideal PidCorrelator (back extrapolation to IP using ideal particle hypothesis) produces a much sharper peak than with the default pion hypothesis. It seems a bit strange to me that the phi-phi invariant mass shows the same behaviour... however I will run the ideal pid correlator for tpc.

I will check the same also with stt.
