Distribution of noise parameters for PID 3401 of radiometer 20M, one of the 70 GHz channels, for fixed s_tot and g. Dashed red lines correspond to results obtained without an active prior, while the solid line corresponds to results after including the active priors on f_knee and α from Eqs. (23) and (24). The black cross indicates the best fit values derived by the DPC pipeline for this radiometer.
