Geometry Differential: y2006g vs y2006h
Material balance in y2006g (old model of the TPC), averaged over 30 degrees in phi. Daughter volumes one level below the mother volume are displayed.
Z sample invariant mass
At Matt Walker's request, I re-ran the code that computes the Z invariant mass from the 500GeV L2W data, using 'ofl' gains instead of 'sim' that had been used before.
SC and GL TPC Calibration pp200 2009
For graduate students performing the Space Charge and Grid Leak calibration for future runs, you will find a how-to-guide in the attached pdf file.
Comparison of Victor's AgSTAR TPC geometry and Yuri's Root/TGeo TPC geometry
Geometry Differential Framework [third test, material balance for TPCe04]
Abstract: To further test the prototype geometry differential framework, it is useful to examine the latest version of the TPC geometry using Yuri's ROOT/TGeo/VMC implementation.
STAR upgrade meeting
Brookhaven National Lab, ITD conference room, at 14:00 (GMT), duration : 09:30
The meeting will focus on the newer proposed upgrades, presentations, observation from the review committees, and how this all fits into the broader picture of the future program

Ilya C: Victor sent a note saying things were working to some list, somewhere.
vernier scan with double-gaussian effective fit.
I've had a lot of trouble stabilizing the fit with the two-gaussian beam profile (narrow gaussian + wide gaussian), so I've moved to something simpler - assuming a two-gaussian vernier scan p

readiness of SL09g for W-production (1)
Preparation for W-production in December 8, 2009
A single daq file from every run used for pp500 W analysis was produced with the chain:

Upsilon Efficiency versus eta-phi for electron daughter
Upsilon 1S+2S+3S used, weighted with:
(TMath::Gaus(upsRap)*upsPt/(exp(upsPt/2.2)+1)
I did not use just |UpsRap|<=0.5 to increase statistics
