Differences between 2018 (PR3) and 2015 (PR2) frequency maps in I, Q, and U. Maps are smoothed to 1° angular resolution for I and to 3° for Q and U, in order to highlight large-scale features. Differences are clearly evident at 30 and 44 GHz, and are mainly due to changes in the calibration procedure.
