Recovered offset coefficients as a function of analysis iteration for a two-band simulation. The true input values are shown as dashed horizontal lines. The values change between iterations because spurious dipoles bias the slope of the T−T plots; iterative dipole correction remove this bias. Overall, the method reproduces the true input values to ≲1 μK. However, the adopted bootstrap uncertainties tend to underestimate the uncertainties in the sub-dominant channels (44 GHz in this case), and are only intended to give an indication of the true uncertainties. End-to-end simulations are required for fully reliable uncertainty estimation.
