Left column: examples of band-limit requirements for unlensed CMB and lensing potential as a function of obtainable accuracy, assuming they are equal, on several multipoles of lensed T, E and B spectra. Right column: summary of the optimized choice of bandwidth parameters for CMB (dot-dashed) and Φ field (dashed) compared with the cost function of the algorithm, as defined in Eq. (22). The diagonal bandwidth parameters are shown as a solid line for comparison.
