Spitzer Observations of Abell 1763. I. Infrared and Optical Photometry
Abstract
We present a photometric analysis of the galaxy cluster Abell 1763 at visible and infrared wavelengths. Included are fully reduced images in r', J, H, and K_s obtained using the Palomar 200in telescope, as well as the IRAC and MIPS images from Spitzer. The cluster is covered out to approximately 3 virial radii with deep 24 μm imaging (a 5σ depth of 0.2 mJy). This same field of ~40' × 40' is covered in all four IRAC bands as well as the longer wavelength MIPS bands (70 and 160 μm). The r' imaging covers ~0.8 deg^2 down to 25.5 mag, and overlaps with most of the MIPS field of view. The J, H, and K_s images cover the cluster core and roughly half of the filament galaxies, which extend toward the neighboring cluster, Abell 1770. This first, in a series of papers on Abell 1763, discusses the data reduction methods and source extraction techniques used for each data set. We present catalogs of infrared sources (with 24 and/or 70 μm emission) and their corresponding emission in the optical (u', g', r', i', z'), and near- to far-IR (J, H, K_s , IRAC, and MIPS 160 μm). We provide the catalogs and reduced images to the community through the NASA/IPAC Infrared Science Archive.
