here is more data on 2009 (attached).

Using StRandomSelector to Artificially Reduce Track Efficiency

In order to better estimate the error in the jet energy scales arising from Tpc efficiency error, we have been looking into the possibility of examining the effects of reducing jet efficiency artif

absolute cross section notes 5

Here is the procedure I'm using to compute the absolute cross section:

With the first couple getAllRuns_xxx.pl files completed, and the findBXoff.C run over them, it was time to begin analysis to ensure that everything was working just fine.

Linearity Check in fixed ecalgeo.g

Abstract:  A bug in the EEMC geometry has been identified.  Lines such as "Material Air isvol=0" have an unexpected (read undocumented) behavior: they create a new materi
