Marginal means and 68% error bars on the cosmological parameters for PlikTT combined with SimAll, when removing either a single cross-spectrum, or all cross-spectra that include a given frequency channel. Shifts in cosmological parameters are in agreement with expectations. Grey bands represent the expected deviation with respect to the full-frequency case, computed from Eq. (61). For comparison, we also show the case PlikTT,EE,TE+SimAll.
