Hi Stefano,

I can now answer for few selected items.

With STT mode general feature of psi3770 looks quite good.
Please have a look attached plots, that are produced with stt mode.

I have definitive problem with 4C fitter, maybe I have to check the track list again as you suggested.
But I have no overlapping of track ID(reconstructed) if I correctly defined track candidates.

That is one of simple solution.
But sometimes momentums are quite similar, there are no clean separation in the momentum range.

Quote:

You should not reject nthose events, but simply take the best cadidate, with momentum closer to the mc one. This would save you a lot of tracks.

I don't know why the huge difference between stt and tpc are existed...

Best regards,
Donghee
