OVRO-LWA Sky Maps These eight brightness-temperature maps were made by Tikhonov-regularized m-mode analysis imaging with the Owens Valley Radio Observatory Long Wavelength Array. Each has 50,331,648 NSIDE-2048 pixels, with coverage nominally north of declination -30 degrees. They are harmonically filtered products: each map has a00 = 0, all m = 0 spherical-harmonic modes removed, and m = 1 modes with l > 100 filtered to suppress terrestrial interference. Large-scale structure… See the full description on the dataset page: https://huggingface.co/datasets/astro-legacy-archive/ovro-lwa-sky-maps.
