where the date is given in the first three columns, the polarizations for 2 definitions of the target angle and their average are presented in the columns called "Pol 1" etc., and the additional attenuation parameter is shown in the column called "loss".

The Moller results, along with the Mott polarimeter results and indications of injector changes are presented on a plot.
