This has recently been measured to be non-zero at a statistical significance of $3.6\\sigma$ in the official Planck PR4 and 9-year WMAP data. In this work, we constrain $\\beta$ using the reprocessed BeyondPlanck LFI and Cosmoglobe DR1 WMAP polarization maps. These novel maps have both lower systematic residuals and a more complete error description than the corresponding official products.
