Full-resolution CMB temperature constrained realization maps. Top: single constrained realization, sⁱ, drawn from P(s ∣ d, C_ℓ, …). Middle: posterior mean map, ⟨s⟩, as evaluated from the ensemble of constrained CMB realizations; note that the small-scale signal amplitude inside the mask decreases smoothly to zero with increasing distance from the edge of the mask. Bottom: CMB posterior standard deviation map, as evaluated pixel-by-pixel from the ensemble of constrained CMB realizations. This map is dominated by instrumental noise outside the mask and by random fluctuations informed by the assumptions of isotropy and Gaussianity inside the mask. The CMB Solar dipole has been removed from the top two panels.
