Angular power spectra of reconstructed lensing field shown as a solid blue line. The mean field effect on the EB estimator for MF maps for d10s5 and HILC-cleaned maps for d10s5 and d12s7 are shown as solid red, green, and grey lines, respectively. The mean-field effect on the EE estimator for HILC-cleaned maps of d10s5 is shown as a solid cyan line. Theoretical lensing power spectra are shown as solid black lines. The dashed magenta line is the sum of theory power spectra and lensing reconstruction noise terms, N⁽⁰⁾ and N⁽¹⁾, shown as dashed (orange) and dash-dotted (purple) lines, respectively.
