- (Figure 1.) distribution using Monte Carlo corrected phototube calibration factors
- (Figure 2.) Plots of Z for different beam energy cuts where :
Figure 2.
- (Figure 3.)Means vs E_{beam} from Gaussian fits of z from Monte Carlo corrected data
- (Figure 4.)Sigma vs E_{beam} from Gaussian fits of z from Monte Carlo corrected data. The curve is a fit to the function a/sqrt(E[Gev]) + b where and a = 0.046 +/- 0.005 and b = 0.033 +/- 0.005. This is very similar to Alex's note from December 16, 2006 where a = 0.050 and b = 0.020.
