Comparison of the Planck 2018 CMB polarization maps in the BICEP2/Keck region

We examine the statistical properties of polarization maps from Planck 2018 within the patch of sky observed by the BICEP2/Keck experiment using the one point distribution function (1PDF), skewness, and kurtosis statistics. Our analysis is…
