Revised SC & GL were uploaded to DB on May 25, 2012.  The following BFC was used to process single st_W daq file from all reasonable runs for days [78-109],

From reco events only prim tracks with pT>1 GeV/c were selected , for which mean chi2/dof for global compnent was computed (fig 1 top). The 2D distrib of chi2/dof vs. run # is shown in fig 1 bottom)

Fig 1. chi2/dof vs. run, calib May 25, 2012 . Run list for the X-axis is in the attachment A.

Fig. 2 shows probability of finding prim vertex per L2WB triggered event. The dashed lines is plotted at Y=0.9 - at the expected efficiency of PPV.

Fig. 3 shows the ratio of VF yield to acquired zeroB_events vs. run index. It is good measure of reco vertex per STAR up-time.

Fig. 4 comparison of the average chi2/dof for good global tracks for pp500 data taken in 2009,11, and 12.
