Near-ultraviolet sources in the Hubble Ultra Deep Field: the catalog. Voyer E.N., De Mello D.F., Siana B., Gardner J.P., Quirk C., Teplitz H.I. <Astron. J., 138, 598-605 (2009)> =2009AJ....138..598V
ADC_Keywords: Surveys ; Galaxy catalogs ; Ultraviolet Keywords: galaxies: evolution - galaxies: formation - galaxies: starburst Abstract: The catalog from the first high-resolution U-band image of the Hubble Ultra Deep Field, taken with Hubble's Wide-Field Planetary Camera 2 through the F300W filter, is presented. We detect 96 U-band objects and compare and combine this catalog with a Great Observatories Origins Deep Survey B-selected catalog that provides B, V, i, and z photometry, spectral types, and photometric redshifts. We have also obtained far-ultraviolet (FUV, 1614Å) data with Hubble's Advanced Camera for Surveys Solar Blind Channel (ACS/SBC) and with GALEX. We detected 31 sources with ACS/SBC, 28 with GALEX/FUV, and 45 with GALEX/NUV. The methods of observations, image processing, object identification, catalog preparation, and catalog matching are presented. Description: The U-band observations were obtained with the HST Wide-Field Planetary Camera 2 (WFPC2) in the Cycle 13 HST Treasury proposal (Teplitz, Program 10403). The UDF was imaged in the near-UV (NUV) through the WFPC2/F300W filter (λmax=2987Å and δλ=740Å) in 12 HST orbits divided into 4 roll angles to compensate for the shape of the WFPC2 chevron and achieve uniform depth. FUV imaging was also obtained in this proposal with HST/ACS Solar Blind Channel (SBC) camera at which time WFPC2 parallel observations were also made. The UDF ACS/SBC images were taken in 50 HST orbits using the long-pass quartz filter (F150LP; λeff=1614Å and FWHM=177Å). The U-band catalog, including U, FUV, B, and BVi postage stamp images of each source, is available online at http://goods.gsfc.nasa.gov/release/UDF_F300W/original/gallery/udf_u_fuv.html File Summary:

Note (1): Notes as follows: a = X-ray source Koekemoer et al. (2004ApJ...600L.123K) b = Source is outside the UDF footprint c = Confusion in GALEX image d = Star Note (2): Spectral types from the GOODS B-selected catalog based on spectral energy distributions (SED) from Coleman et al. (1980ApJS...43..393C) and Kinney et al. (1996ApJ...467...38K). * Type 1 galaxies are early-types (E, S0, and Sa), * Type 2 are Sbc, * Type 3 are Scd, * type 4 are irregulars, * types 5 and 6 are starbursts SB1 and SB2.
