Eight-year Full-depth unWISE Coadds
Abstract
We present deep, full-sky maps built from Wide-field Infrared Survey Explorer and NEOWISE exposures spanning the 2010 January-2020 December time period. These coadds, which incorporate roughly 8 yr of W1 (3.4 μm) and W2 (4.6 μm) imaging, are the deepest ever full-sky maps at wavelengths of 3-5 μm. Photometry based on these coadds will be a component of DESI Legacy Imaging Surveys DR10.
