It is informative to look at the individual fits as a part of troubleshooting the background-subtraction issues we have encountered. Here I post some examples of the x_F binned distributions. Altogether, there are 180 plots. While this is too much to post in one blog entry, I have chosen x_F bin-1 as the first bin which seems to give a completely ridiculous answer for x_F < 0. The rest of the plots are located at the STAR protected page.
