Notes. The fit was performed on the joined Q and U maps from the Planck PR3 353 GHz data. The error bars correspond to the standard deviations of the 1D marginalized posterior distributions. The last two columns give the reduced χ2 and the effective polarization fraction obtained for the best fits (see text).
