Difference between the BEYONDPLANCK polarized synchrotron amplitude and the raw WMAP K-band map (Bennett et al. 2013), with the latter scaled to 30 GHz assuming a spectral index of βs = −3.1 (top panel). Similar difference between the BEYONDPLANCK and Planck DR4 (Planck Collaboration Int. LVII 2020) synchrotron amplitude maps (bottom panel). Left and right columns show Stokes Q and U parameters respectively, and all maps are smoothed to a common angular resolution of 3° FWHM.
