Pseudo-spectrum standard deviation for each instrumental systematic correction shown in Fig. 12 (thin colored lines). For comparison, thick black lines show spectra for the mean of the full frequency map; thick red lines show their standard deviations (i.e., the full systematic uncertainty); and gray lines show white noise realizations. Columns show results for K, Ka, Q1, and W4, respectively, while rows show results for each of the six polarization states (TT, EE, BB, TE, TB, and EB). All spectra have been derived outside the CMB confidence mask presented by Andersen et al. (2023) using the HEALPix anafast utility, correcting only for sky fraction and not for mask mode coupling.
