Plots of all the noise for the expected null combinations of TB, EB, and BB for the region outside the P06 mask. For T the foreground‐cleaned V and W bands have been combined bands. For E and B, the foreground‐cleaned Q and V bands have been combined. Cosmic variance is included for all plots. For each plot there are 999 ﹩l﹩‐values that have been averaged into 33 bins for TB and 12 bins for EB and BB. For TB, ﹩\chi ^{2}/ \nu =41.6/ 33﹩ and ﹩\chi ^{2}/ \nu =931/ 999﹩ with corresponding ﹩\mathrm{PTE}\,=0.15﹩ and 0.94 for the two binnings. For EB, ﹩\chi ^{2}/ \nu =7.5/ 12﹩ and ﹩\chi ^{2}/ \nu =956/ 999﹩ with corresponding ﹩\mathrm{PTE}\,=0.82﹩ and 0.84. For BB, ﹩\chi ^{2}/ \nu =6.2/ 12﹩ and ﹩\chi ^{2}/ \nu =1000/ 999﹩ with corresponding ﹩\mathrm{PTE}\,=0.91﹩ and 0.49. The polarization maps have been cleaned as described in § 4.3. See also Table 6.
