The Wide-field Infrared Survey Explorer (WISE) satellite observed the full sky in four mid-infrared bands in the 2.8-28 μm range. The primary mission was completed in 2010. The WISE team has done a superb job of producing a series of high-quality, well-documented, complete data releases in a timely manner. However, the "Atlas Image" coadds that are part of the recent AllWISE and previous data releases were intentionally blurred. Convolving the images by the point-spread function while coadding… Expand
Full-depth Coadds of the WISE and First-year NEOWISE-Reactivation Images
The Near Earth Object Wide-field Infrared Survey Explorer (NEOWISE) Reactivation mission released data from its first full year of observations in 2015. This data set includes ~2.5 million exposuresExpand
unWISE Coadds: The Five-year Data Set
We present full-sky coadded maps created by uniformly combining the first five years of Wide-field Infrared Survey Explorer (WISE) and NEOWISE imaging at 3.4 microns (W1) and 4.6 microns (W2). ByExpand
WISE photometry for 400 million SDSS sources
We present photometry of images from the Wide-Field Infrared Survey Explorer (WISE; Wright et al. 2010) of over 400 million sources detected by the Sloan Digital Sky Survey (SDSS; York et al. 2000).Expand
Deep Full-sky Coadds from Three Years of WISE and NEOWISE Observations
We have reprocessed over 100 terabytes of single-exposure WISE/NEOWISE images to create the deepest ever full-sky maps at 3-5 microns. We incorporate all publicly available W1 and W2 imaging - aExpand
The unWISE Catalog: Two Billion Infrared Sources from Five Years of WISE Imaging
We present the unWISE Catalog, containing the positions and fluxes of roughly two billion objects observed by the Wide-field Infrared Survey Explorer (WISE) over the full sky. The unWISE Catalog hasExpand
Deep co-added sky from Catalina Sky Survey images
A number of synoptic sky surveys are underway or being planned. Typically, they are done with small telescopes and relatively short exposure times. A search for transient or variable sourcesExpand
The Faintest WISE Debris Disks: Enhanced Methods for Detection and Verification
In an earlier study, we reported nearly 100 previously unknown dusty debris disks around Hipparcos main-sequence stars within 75 pc by selecting stars with excesses in individual WISE colors. Here,Expand
Six-year Static Sky unWISE Coadds
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 dataExpand
Time-resolved WISE/NEOWISE Coadds
We have used the first ~3 years of 3.4 micron (W1) and 4.6 micron (W2) observations from the WISE and NEOWISE missions to create a full-sky set of time-resolved coadds. As a result of the WISE surveyExpand
The structure of the Milky Way based on unWISE 3.4 μm integrated photometry
We present a detailed analysis of the Galaxy structure using an unWISE wide-field image at $3.4\,\mu$m. We perform a 3D photometric decomposition of the Milky Way taking into account (i) theExpand

Combining Undersampled Dithered Images
Undersampled images, such as those produced by the HST WFPC-2, misrepresent fine-scale structure intrinsic to the astronomical sources being imaged. Analyzing such images is difficult on scales closeExpand
