x1 vs pt in simulation continued

Previously I made a blog entry about x1 vs Pt in simulation data, with and without requiring a trigger fired. You can find that here:

Run-12 Transverse Jets: Trigger QA (Full Production, Second Pass)

I have rerun a goodly number of the μDST's which did not finish properly. At this point I am satisfied to set a number of cuts and move on to the next step.

As a follow-up to achieve the request to modify PPV to improve efficieny

Run-11 Transverse Jets: First Look at Sivers Polarization Correction (Full Statistics)

I have finally applied polarization-correction to the Sivers asymmetries for the "all triggers" sample. I utilized a weighted-average techniqe as follows:

Calibrating VPD + 'TOF' for pp510 run 12

The goal of this pp510 calibration was to create a calibration based on run12's UU193 barrel calibration and the dE/dx calibration request.  The reason why we want to use the barrel calibration i

pp 500 GeV 2013 optimization of rates

Rate limit at pp 500 GeV in 2013 appears to be ~1.1 GB/s, which is where the "trigger deadtime" starts to kick in as tokens aren't released fast enough.

Minor updates since February

List of some minor updates since February. For each update, I carefully did one step at a time and checked various plots of the analysis to determine the effect it had, and whether the effect was reasonable (i.e. that I had not introduced any bugs).  No bugs found.

Additive vs Multiplicative

In the Equations of this other blog, it was noted that the effect of pi0s generated outside [n1,n2] and smeared
