VIMOS Ultra Deep Survey (VUDS) DR1
Listed in IVOA Registry (Virtual Observatory)
This paper describes the first data release (DR1) of the VIMOS Ultra Deep Survey (VUDS).
Description
The VUDS-DR1 is the release of all low-resolution spectroscopic data obtained in 276.9 arcmin^2^ of the CANDELS-COSMOS and CANDELS-ECDFS survey areas, including accurate spectroscopic redshifts z_spec_ and individual spectra obtained with VIMOS on the ESO-VLT. A total of 698 objects have a measured redshift, with 677 galaxies, two type-I AGN, and a small number of 19 contaminating stars.
The targets of the spectroscopic survey are selected primarily on the basis of their photometric redshifts to ensure a broad population coverage. About 500 galaxies have z_spec_>2, 48of which have z_spec_>4; the highest reliable redshifts reach beyond z_spec_=6. This data set approximately doubles the number of galaxies with spectroscopic redshifts at z>3 in these fields.

We discuss the general properties of the VUDS-DR1 sample in terms of the spectroscopic redshift distribution, the distribution of Lyman-{alpha} equivalent widths, and physical properties including stellar masses M* and star formation rates derived from spectral energy distribution fitting with the knowledge of z_spec_. We highlight the properties of the most massive star-forming galaxies, noting the wide range in spectral properties, with Lyman-{alpha} in emission or in absorption, and in imaging properties with compact, multi-component, or pair morphologies.
We present the catalogue database and data products. All VUDS-DR1 data are publicly available and can be retrieved from a dedicated query-based database. Future VUDS data releases will follow this VUDS-DR1 to give access to the spectra and associated measurement of ~8000 objects in the full ~1 square degree of the VUDS survey.
