Notes. We give results for 30 GHz, 44 GHz, and 70 GHz full mission frequency maps, and for various 70 GHz subsets (for full and independent destriping options, for pure white noise, ideal and realistic simulations). For the rightmost column we rescaled the NCVM by the inverse of χ2 and re-run the K-S test for realistic simulation. The χ2 result for this case is by construction exactly one.
