Early Studies

Basic QA Plots

Select a trigger and charge combination to view QA summary plots. Each point on a plot is a mean value of that quantity for the given run, while the error is sqrt(nentries).

Problems Worth Noting

Drop in nHitsFit and jump in DCA for associated globals for days 140 - 142. The jet group has already studied this problem and reported it to starcalib. Fixing it will require a reproduction. Unfortunate, as it's a significant chunk of stats.
Group of ~3 runs from day 134 with low <pt>, low <eta>, high <vz> and small in shifts in <dEdx> and <nsigmapion>. Looks like a hot tower; I can't remember if this has already been identified or not.
Comparison to Run 5 -- the mean values for dE/dx and nsigmapion are significantly different in Run 5 and Run 6. Need to investigate this further. For example, compare the following jet patch trigger plots for charge-summed pions. Run 5 is on the left, Run 6 on the right. They both start out around -0.4, but Run 5 drifts towards -0.7 while Run 6 climbs towards -0.3.

Data Collection

Runlist query:

get_file_list.pl -distinct -keys 'orda(runnumber)' -cond 'production=P06ie,trgsetupname=ppProductionLong,sanity=1,tpc=1' -limit 0 

This query yields 406 runs (3 with emc=0) which I process with star-submit-template. I'm using Murad's production of StJetSkimEvents to get all event-level info, so my chain is brutally simple: just StMuDSTMaker and a simple set of track quality cuts, viz.

pT > 2 GeV/c
|eta| < 2.1

Current working directory (PDSF):

/home/kocolosk/analysis/run6/may03

Once I've got these trees back at MIT I merge them with the jetSkimEvent trees using an index on (run,event) (see Common Analysis Trees). I also apply some more stringent cuts:

Event-level cuts

spinDB reports all OK
nVertices > 0 and z-position of best vertex inside 60cm

Track cuts

pT > 2. GeV/c
|eta| < 1.
|DCAglobal| < 1.
nHitsFit >= 25
nSigmaPion in [-1,2]

Single Spin Asymmetries by Fill

BJP1 (hardware & software & geometric) requirement, only use pions with dR > 1.5
