For a list of all services and tables belonging to this service's resource, see Information on resource 'VIPERS DR2 Spectra'
The VIMOS Public Extragalactic Redshift Survey (VIPERS [1]) is a complete ESO Large Program that has mapped in detail the three-dimensional distribution of the global population of galaxies brighter than i=22.5 magnitude over the redshift range 0.5 < z < 1.2.
This resource contains the spectra of the second data release (PDR-2). For more information, please refer to the VIPERS web site [1].
We kindly request all papers using VIPERS data to add the following text to their acknowledgement section: This paper uses data from the VIMOS Public Extragalactic Redshift Survey (VIPERS). VIPERS has been performed using the ESO Very Large Telescope, under the "Large Programme" 182.A-0886. The participating institutions and funding agencies are listed at http://vipers.inaf.it
