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
