Final results (255 GeV)

Note: These values have changed now that the full analysis is complete, and the A_N combined for all of the runs is used instead of the A_N measured fill-by-fill. The previous values were systematically incorrect, due to assumed Gaussian errors on the run-by-run A_N used in the denominator, which causes problems when the errors are large. In addition to using the combined A_N, these new results use a higher order calculation of the mean and standard deviation of the ratio of the asymmetries with respect to the beam and target (See http://www.stat.cmu.edu/~hseltman/files/ratio.pdf)
