Unlike-sign asymmetry

There must have been a mismatch between the definition Joe used for R_5 and R_6 and what I was expecting. When I swapped the R_5 and R_6 values provided by Joe for each run, the unlike-sign asymmetry goes to 0 (see attached plots).

Relative Luminosity systematic value

In light of the above result, I intend to continue to use the relative luminosity uncertainty value described in Joe's presentation found here. The method used to calculate the uncertainty is consistent with the method used for the 2006 results, which is described by Murad here.
