2002AJ....123.2206P GALAXIES ASSOCIATED WITH z ~ 4 DAMPED Ly{alpha} SYSTEMS. I. IMAGING AND PHOTOMETRIC SELECTION JASON X. PROCHASKA, ERIC GAWISER, ARTHUR M. WOLFE, ANDREAS QUIRRENBACH, KENNETH M. LANZETTA, HSIAO-WEN CHEN, JEFF COOKE, AND NORIAKI YAHATA Received 2001 October 18; accepted 2002 January 22 ABSTRACT This paper describes the acquisition and analysis of imaging data for the identification of galaxies associated with z ~ 4 damped Ly{alpha} systems. We present deep BRI images of three fields known to contain four z ~ 4 damped systems. We discuss the reduction and calibration of the data, detail the color criteria used to identify z ~ 4 galaxies, and present a photometric redshift analysis to complement the color selection. We have found no galaxy candidates closer to the QSO than 7" that could be responsible for the damped Ly{alpha} systems. Assuming that at least one of the galaxies is not directly beneath the QSO, we set an upper limit on this damped Ly{alpha} system of L < L*_LBG_/4. Finally, we have established a Web site to release these imaging data to the public. Key words: galaxies: formation
