I ran the gamma maker over the filtered MC QA sample.  Had no difficulties in making gamma trees.  I don't see anything fishy about the plots.  I'm hoping to add some plots that will compare the QCD to data soon, but I don't think it's necessary right now to say the sample looks OK.

The one thing I couldn't check well was the bfc log file.  I don't know what to look for in the mountain of text.

Plots are attached of all QCD bkg samples weighted together by luminosity and all photon signal samples weighted together by luminosity.  It's also notable that the distributions looks pretty smooth and I don't see evidence of any of them not playing well together.

Update 25 August 2010

After the two highest partonic pT bins of the single sample were complete I ran the same code.  Attached are 3 pdfs. rcf00074 has plots for each of the 10 sections of that sample, rcf0075 has plots for each of the 10 sections of that sample, and the Aug23QA has all sections added together, and the bins combined with the appropriate weight.
