The Cycle 23 COSMOS-DASH program (Program ID: GO-14114) is a 0.49deg^2 survey of the COSMOS field using the HST-WFC3 F160W filter. It consists of 456 pointings in 57 orbits (8 pointings per orbit) obtained between 2016 November and 2017 June using the Drift And SHift (DASH; Mowla+ 2019ApJ…880…57M) technique.data set additionally includes all available archival F160W data in COSMOS, including CANDELS, resulting in a total F160W area of 0.66deg^-2. We use an updated, redrizzled mosaic (containing more archival data) that has a pixel scale of 0.1”/pix (see Figure 1).the 262,615 objects identified in the UVISTA catalogs of Muzzin+ 2013 (J/ApJS/206/8), 51586 have coverage with the COSMOS-DASH F160W observations.(1 data file).
