Mean r with (16,  84)% credible intervals from 500 simulations, applying the three nominal component separation pipelines plus extensions. We assume the d0s0 foreground scenario with baseline white noise level and optimistic 1/f component. Cross markers with smaller error bars correspond to homogeneous noise across the SAT field of view and dot markers with larger error bars correspond to inhomogeneous noise. The relative increase in σ(r) between both is shown in the bottom panel.
