Caltech Faint Galaxy Redshift Survey. IX. Source Detection and Photometry in the Hubble Deep Field Region
Abstract
Detection and photometry of sources in the U_n, G, ℛ, and K_s bands in a 9 × 9 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. The galaxy number density is 1.3 × 10^5 deg^(-2) to ℛ = 25.0 mag. Galaxy number counts have slopes d log N/dm = 0.42, 0.33, 0.27, and 0.31 in the U_n, G, ℛ, and K_s bands, consistent with previous studies and the trend that fainter galaxies are, on average, bluer. Galaxy catalogs selected in the ℛ and K_s bands are presented, containing 3607 and 488 sources in field areas of 74.8 and 59.4 arcmin^2, to ℛ = 25.5 and K_s = 20 mag.

© 2000 American Astronomical Society. Received 1999 July 26. Accepted 1999 October 25. The Hubble Deep Field (HDF) database was planned, taken, reduced, and made public by a large team at the Space Telescope Science Institute headed by B. Williams. We thank the referee, A. Dressler, for timely and helpful criticism. This study is based on observations made at the Palomar Observatory, which is owned and operated by the California Institute of Technology; and with the NASA/ESA Hubble Space Telescope, which is operated by AURA under NASA contract NAS 5-26555. Primary financial support was provided under NSF grant AST 95-29170. Some additional support was provided by Hubble Fellowship grants HF-01093.01-97A and HF-01099.01-97A from STScI, which is operated by AURA under NASA contract NAS 5-26555.Attached Files
