 -------- Loose notes, needs cleanup, Jan

Lidia's most recent test prodcution of 3 runs (89 files) also had
CTB matching off

 Low Lumi (run9060086), Mid Lumi (run9069059), High Lumi (run 9068124)

Akio's event classification  txt file from 3 files (with differnt luminosity) at the bottom of

http://www.star.bnl.gov/protected/spin/akio/200806/index_5th.html

from Lidia's test production. I checked that I get identical results
with Jan's production and Lidia's for the low lumi run.

-------------

Just remind you that there is "accidental match" between VPD and
TPC vertex up to ~25% (@ high lumi) under the peak.

* could you show Rosi how to print VPD & BBC vertex position in BFC?

Once Mudst is created, you can get VPD vertex (from TOF electronics) by
   StMuEvent->vpdVz()

For BBC I have not yet implemented the calibrated vertex. Once done,
one should be able to get it from
   StEvent->triggerDetectorCollection()->bbc()->zVertex()

--------- Rosi ---------

While I was doing this, I spun a macro over the MuDst in the folder
above and duplicated some of Akio's results, just to make sure I
understand.

 


So here are the z positions of the ranks 1 and 2 vertices and the vpd:
