NEOWISER W1 survey collection

Funded by NASA's Planetary Science Division, NEOWISE harvests measurements of asteroids and comets from the WISE images and provides a rich archive for searching WISE data for solar system objects. Here we update our full-depth coadds by folding in the most recently published year of W1/W2 exposures released by NEOWISER.

These new single-frame data were acquired between 2015 December 13 and 2016 December 13, and became public in 2017 June. In the present work, we simply re-ran the latest unWISE coaddition code (Meisner et al. 2017a) on inputs including this additional year of publicly available NEOWISER frames. The resulting set of full-depth coadds uniformly incorporates all publicly available W1 and W2 exposures, with observation dates ranging from 2010 January 7 to 2016 December 13.
