The STAR experiment

The spill-over plots from the previous post raise the question of why the partonic pT spreads so much.  These new plots show more detail on the pT contributions at each stage of the event.

1. Specify runs / timestamps to simulate

As Will pointed out, you can't always say with 100% certainty whether a given module is showing banding structure just by looking at the raw ADC vs.

Below are x1 and x2 distributions for different eta bins. eta3 is always the larger of the two jet etas.

These plots were made from data taken from the  following runs:
 8335112
 8336019
 8336028
 8336044
 8336052
 8336062

It doesn't look like I can remove the spillover events from the training samples without drastically changing their content.  Now I just have to figure out what to do with them to keep the distribution sensible.

Just realized that STAR provides timestamps using GMT, not EDT... so....

We now have the fitting algorithms working for both the LDA and the 2-D approach.  The results are plotted below, marking actual values in black, the 2D values in red, and the LDA values in blue.
