Notes. First three columns show the performance of the best-fit model: the overall χ2 and χ2 per degree of freedom, as well as their breakup between RM and polarisation Q and U maps. The last two columns show the same quantities when the standard deviation within the bins (calculated after removal of outliers) is taken as an error estimate.
