Abstract
We present the first Public Data Release (PDR-1) of the VIMOS Public
Extragalactic Survey (VIPERS). It comprises 57 204 spectroscopic
measurements together with all additional information necessary for
optimal scientific exploitation of the data, in particular the
associated photometric measurements and quantification of the
photometric and survey completeness. VIPERS is an ESO Large Programme
designed to build a spectroscopic sample of ≃100 000 galaxies with
iAB <22.5 and 0.5 <z <1.2 with high sampling rate
(≃45%). The survey spectroscopic targets are selected from the
CFHTLS-Wide five-band catalogues in the W1 and W4 fields. The final
survey will cover a total area of nearly 24 deg2, for a total
comoving volume between z = 0.5 and 1.2 of ≃4 ×
107 h-3 Mpc3 and a median galaxy
redshift of z ≃ 0.8. The release presented in this paper includes
data from virtually the entire W4 field and nearly half of the W1 area,
thus representing 64% of the final dataset. We provide a detailed
description of sample selection, observations and data reduction
procedures; we summarise the global properties of the spectroscopic
catalogue and explain the associated data products and their use, and
provide all the details for accessing the data through the survey
database (http://vipers.inaf.it)
where all information can be queried interactively.
Based on observations collected at the European Southern Observatory,
Cerro Paranal, Chile, using the Very Large Telescope under programs
182.A-0886 and partly 070.A-9007. Also based on observations obtained
with MegaPrime/MegaCam, a joint project of CFHT and CEA/DAPNIA, at the
Canada-France-Hawaii Telescope (CFHT), which is operated by the National
Research Council (NRC) of Canada, the Institut National des Sciences de
l'Univers of the Centre National de la Recherche Scientifique (CNRS) of
France, and the University of Hawaii. This work is based in part on data
products produced at TERAPIX and the Canadian Astronomy Data Centre as
part of the Canada-France-Hawaii Telescope Legacy Survey, a
collaborative project of NRC and CNRS. The VIPERS web site is http://vipers.inaf.it/
