WMAP Nine-Year Frequency Band Maps This dataset contains the five WMAP nine-year RAW, rather than foreground-reduced, coadded frequency-band sky maps. Each source file contributes a Stokes Maps config containing full-sky Stokes I, Q, and U measurements and observation counts, and a separate Weight Arrays config containing its polarisation weights. The nominal frequencies are K = 23 GHz, Ka = 33 GHz, Q = 41 GHz, V = 61 GHz, and W = 94 GHz. LAMBDA describes the coaddition: "The… See the full description on the dataset page: https://huggingface.co/datasets/astro-legacy-archive/wmap-band-maps-9yr.
