Dear Gene

Thanks for the explanation of the big step at the middle of z distribution of tpc hit. 

The reason why I asked was the step is just about factor of two compared to the 

outer z region, which sounded like they are all actual good hits, but just plotted 

overlapped at the middle caused by the long drift time converted to the z position. 

But you say they are mostly caused by pile-up, does this mean the most of the 

recorded hits are pile-up hits compared to the real hits from the triggered collision, 

even in this low luminosity of ~40kHz leveled rate? Could you please remind me 

the full drift timeof 2m (close to 50 us)? A few pile up (within this time window) in 

each event might be real collisions though… Thanks again. 

Best regards, ShinIchi

Dear QA team,

Sorry for today's confusion about the QA meeting. I did not

communicate with Ashik about what fast-offline intended

to present.
