Description
Detection and photometry of sources in the U_n_, G, {R}, and K_s_ bands in a 9x9 arcmin^2^ region of the sky, centered on the Hubble Deep Field, are described. The data permit construction of complete photometric catalogs to roughly U_n_=25, G=26, {R}=25.5, K_s_=20 mag and significant photometric measurements somewhat fainter. Galaxy catalogs selected in the {R} and K_s_ bands are presented, containing 3607 and 488 sources in field areas of 74.8 and 59.4arcmin^2^, to {R}=25.5 and K_s_=20mag.
