Maps of CMB plus foregrounds at S3 150 GHz. First row: Input B-mode CMB and foregrounds without beam systematics (left), CMB plus foregrounds with beam systematics (middle) and after deprojection (right). Second row: Difference between the deprojected map and the input map without beam systematics for the T (left), E (middle), and B (right) modes. The results of 95 GHz are similar to the 150 GHz results.
