[Takahiro: Silicon seeding for INTT efficiency study]
- There is not such function as random accidental track search or event mixing in default PHActs Silicon seeding library since it is not physics.
- Why don't you use full track including TPC? Some of those DST are already available for p+p Run24 data.
-- You don't need to worry about the TPC calibration for this case, to minimize duplicates.
-- What you need to do is to grab silicon seed and TPC seed info then compare between 1 and 2 INTT clusters.
- Need p+p and Au+Au DST data with half entry chip entries, which are usually rejected by calibration.
-- Need to produce special DST with a special CDB not to exclude half entry chips.
- The best way to trigger random track is to see the silicon seed without matching TPC seed.
-- Mixing cluster with different events and try tracking.
- Suggest to start with MC data with TPC.
- Note that INTT hits are duplicated between different Fun4All events, not first few events but also for entire events.
- TPC seed matching is more reliable for not having the duplication.
