5. Abstract

We propose to process and combine with state-of-the-art tools the majority of the
WFPC2 images obtained as part of Archival Pure Parallel Program, consisting of
observations of over 3, 000 random pointings primarily in the wide WFPC2 UBVI
filters. We will produce combined and cosmic-ray cleaned images, as well as object
catalogs, for over 2, 000 of these pointings. We will use these data 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
M(sun) for about 50 separate lines of sight in the LMC. The same data will be
available to the astronomical community for a wide variety of other investigations,
thus helping realize the legacy of WFPC2 parallel images.
