Combined, drizzled, cosmic-ray cleaned images were produced for each pointing. These data can be used to address a wide range of science topics: measuring the cosmic shear on scales from 20" to 2'; discovering ~ 50 starforming galaxies at z ~ 4; finding optical counterparts to AGNs in wide-area radio and X-ray catalogs; improving the determination of the scale length of the Galactic disk; and studying stellar populations down to 1 solar mass for about 25 separate lines of sight in the Magellanic Clouds. http://archive.stsci.edu/prepds/appp/ Archive Research 2 http://archive.stsci.edu/siap/search.php?id=appp& GET Pointed 360.0 360.0 360.0 360.0 0 0 0 100 HST WFPC2 Optical
