Hi Evgeny,

yes there are likely quite a few pp events which don't leave hits in the TPC - there is no condition that an event leaves any trace in sPHENIX in the simulation. The same can theoretically happen in AuAu, though I don't know if this ever happens in practice.

Hello Chris,
Are those events 0-biased, so that pp events can have 0 hits in the TPC?
That was not the case for AA events, now I am starting to realize why I had some issues with filling the maps.

Cheers,

Hi folks,

the production of 2.5M additional pp events is done and the files are
available. By the end of tomorrow there should be another 1.5M. In total
we'll have 6M by then. Let me know if you need more.

Chris
