Run9 500 GeV BTOW Relative Gains

The relative gains for the BTOW in the run9 500 GeV running were calculated using "Scott's Method" based on the slopes of the ADC spectra.

Ws at STAR Run 9 - algo ver 4.2

Last week  results of W-algo (ver 4.1) from Run 9 data have been presented to spin PWG. Since then one error has been fixed and W-algo was  improved.

2005 Dijet Cross Section Analysis Note

The 2005 Dijet Cross Section Analysis Note is attached.

A presentation for this analysis was made on September 10, 2009 and is available here:
