Initial comparison of Run6/Run9 Pion mass for various detector eta bins

Updated on Tue, 2011-09-13 17:27. Originally created by ncolmena on 2011-09-13 17:27.

 This is a quick initial look at the pion centroid for Run6/Run9 for different detector eta bins. The next look should include a fit for the eta meson peak.

Note that there are 8 total histograms. They are divided into pairs. The first of each pair is Run 6, the second Run 9. Unless otherwise noted, the beginning fit range is 0.03.

Eta of 1.0-1.3:

 

Eta of 1.3-1.5:

 

 

Beginning fit range of 0.05 for both Run6 and Run9:

 

 

Eta of 1.7-2.0: (Beginning fit range of 0.08 for Run 6, 0.07 for Run9)
