We present and publicly release a set of deep, full-sky Wide-field Infrared Survey Explorer (WISE) coadds built from WISE and NEOWISE images spanning from early 2010 through late 2018. This data release uniformly incorporates six years of WISE and NEOWISE exposures at 3.4 μ m (W1) and 4.6 μ m (W2). These inertial “unWISE” stacks allow for detection of roughly a billion stars and galaxies fainter than the AllWISE catalogs sensitivity limit. Importantly, our six-year unWISE coadds, in combination with the crowdsource cataloging software, were used to perform deep source detection/deblending for CatWISE2020.
