| Abstract: |
We present multi-waveband optical imaging data of the Subaru/ XMM-Newton Deep Survey (SXDS). The SXDS has been the focus of wide range of multi-wavelength observing programs spanning the X-ray to the radio. The optical imaging observations are carried out with Suprime-Cam in the course of Subaru Telescope ”Observatory Projects”. A total area of 1.22 square degree is covered in five contiguous sub-fields, each of which corresponds to a single Suprime-Cam field of view (34 × 27 ), in five broadband filters to the depths of B = 28.4, V = 27.8, Rc = 27.7, i′ = 27.7, and z′ = 26.6 (AB, 3-σ, φ-2arcsec). The data are reduced and compiled into five multi-waveband photometric catalogs, separately for each Suprime-Cam field. The i -band catalogs contain about 900,000 objects in total, making the SXDS catalogs one of the largest multi-waveband object catalogs in corresponding depth and area coverage. The SXDS catalogs can be used for an extensive range of astronomical applications such as the number density study of the Galactic halo stars to the large scale structures at the distant universe. The number counts of galaxies are derived and compared with those of existing deep extragalactic surveys. Photometric redshifts of galaxies are estimated based on the optical data combined with near-infrared data derived from UKIDSS/UDS survey. The optical data, the source catalogs presented here are publicly available on the SXDS web page (http://www.naoj.org/Science/SubaruProject/SXDS/index.html). |
