摘要: We present a UV to mid-infrared multi-wavelength catalog in the CANDELS/GOODS-S field, combining newly obtained CANDELS HST/WFC3 F105W, F125W, and F160W data with existing public data. The is based on source detection WFC3 band. mosaic includes from deep wide observations as well previous ERS HUDF09 programs. reaches 5? limiting depth (within an aperture of radius 0.''17) 27.4, 28.2, 29.7?AB for wide, deep, HUDF regions, respectively. contains 34,930 sources representative 50% completeness reaching 25.9, 26.6, 28.1?AB band three regions. In addition bands, also (U both CTIO/MOSAIC VLT/VIMOS), optical (HST/ACS F435W, F606W, F775W, F814W, F850LP), infrared (HST/WFC3 F098M, VLT/ISAAC Ks, VLT/HAWK-I Spitzer/IRAC 3.6, 4.5, 5.8, 8.0 ?m) observations. validated via stellar colors, comparison other published catalogs, zero-point offsets determined best-fit templates spectral energy distribution spectroscopically observed objects, accuracy photometric redshifts. able detect unreddened star-forming (passive) galaxies mass 1010 M ? at level z ~ 3.4 (2.8), 4.6 (3.2), 7.0 (4.2) As example application, used select passive 2-4 Balmer break. It study color-magnitude diagram 0 < 4.
