Notes. This illustrates the order of magnitude of the different errors. The total error contains the cosmic variance and instrumental noise, and also the cirrus residuals (CMB is negligible at this frequency). The contribution of cirrus errors only is given in the sixth column for comparison. The errors linked to the projection of the fields on the tangential plane and those due to the beam, although systematic and not stochastic, are given for convenience in the same units as the total power Cℓ, in Cols. 7 and 8, respectively.
