TL;DR
This paper presents a high-resolution U-band catalog of the Hubble Ultra Deep Field, combining multi-wavelength data from Hubble and GALEX, and details the observational and data processing methods used.
Contribution
It provides the first high-resolution U-band catalog for the Hubble Ultra Deep Field and integrates it with existing multi-wavelength data from other surveys.
Findings
Detected 96 U-band objects in the Hubble Ultra Deep Field.
Combined U-band catalog with B, V, i, z photometry, spectral types, and redshifts.
Identified 31 FUV sources with ACS/SBC and 28 with GALEX/FUV.
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 (GOODS) B-selected catalog that provides B, V, i, and z photometry, spectral types, and photometric redshifts. We have also obtained Far-Ultraviolet (FUV, 1614 \AA) data with Hubble's Advanced Camera for Surveys Solar Blind Channel (ACS/SBC) and with Galaxy Evolution Explorer (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.
