Reconstruction noise power associated with the modulation (blue) and Doppler (red) estimators as a function of the maximum CMB multipole used. The solid lines correspond to the case of noise-free CMB maps, while the dashed lines correspond to the case where the characteristic Planck instrument noise is taken into account. The red dash-dotted horizontal line denotes the expected signal level of the boost due to our local motion, while the blue dash-dotted horizontal line denotes the enhanced boost amplitude as seen by the modulation estimator. The blue dotted line denotes the effective Doppler boost signal as seen by the modulation estimator after accounting for the effects of aberration induced by the boost. Also note that the reconstruction errors shown in red are derived for the total dipole power, rather than the amplitude in a particular direction, and hence are higher by a factor of as compared to the errors for individual directions reported in Planck Collaboration XXVII (2014).
