THE SECOND PUBLIC DATA RELEASE (PDR-2)

This is the entry point to the second and final data release (PDR-2) of the VIMOS Public Extragalactic Redshift Survey (VIPERS). The PDR-2 includes spectroscopic measurements for 91507 objects, together with the survey masks, statistical weights and photometric ancillary information from the VIPERS multi-lambda survey. 89022 of these objects are main survey targets. Details on the data and how to use them can be found in Scodeggio et al. (2018). General information about the survey can be found in Guzzo et al. (2014) and Garilli et al. (2014).


NEW (Oct 2019): Data for the 153 HOD mocks used in all VIPERS clustering analyses are now also available.





VIPERS galaxy data

The VIPERS redshift survey and ancillary data, which can be retrieved in three different ways:

  • An easy-to-use Web interface, providing a fully queryable system, accessible at this LINK (free registration required), which allows the user to select specific objects or sub-samples and data by searching around a position, using a combination of criteria or an object list.
  • Full dataset tar files, available from this page along with the mask files characterising the survey selection function.
  • The ESO Phase-3 archive at this LINK

The following tables contain the PDR-2 spectroscopic catalogues, separately for the two VIPERS fields (W1 and W4). Catalogues are provided as gzipped files and stored in two formats: FITS binary tables and ASCII files. The columns description is shared by W1 and W4 catalogs and described in this PAGE.

The following tables contain the the parent photometric catalogues, separately for the two VIPERS field (W1 and W4). Catalogues are provided as gzipped files and stored in two formats: FITS binary tables and ASCII files. The columns description is shared by W1 and W4 catalogs and described in this PAGE.

Update (Jan 31, 2017): the info originally provided within the two photometric catalogs about the spectroscopic mask was not up to date. It has now been corrected to cover the full spectroscopic survey area.

Here you can download the complete set of PDR-2 spectra. The user can download the 1D spectra (1D) or the 1D and 2D spectra in a single tar.gz file (1D/2D). For format details see the last section (Spectra) of this PAGE.

Two large random catalogues are provided for the two fields W1 and W4, which match the final geometry and footprint of the VIPERS spectroscopic data. Only sky positions are provided. The footprints have been applied by using the Venice code (https://github.com/jcoupon/venice).

VIPERS mock catalogues

In the following is provided the suite of VIPERS mock catalogues built from the BigMultiDark simulation (Klypin et al. 2016), where dark matter haloes have been populated with VIPERS-like galaxy using a HOD prescription. For each mock, both a "parent" and a "masked" version, fully reproducing the VIPERS geometry and footprint, are provided. The survey mask and a random catalogue are also included in the package. Details are provided in a readme file. The adopted HOD prescription is described in de la Torre et al. 2013, A&A, 557, A54, while further details are provided in de la Torre et al. 2017, A&A, 608A, 44D.

  • Rectangular sky coverage (no mask)

  • Follow VIPERS redshift distribution

  • VIPERS redshift errors are not included

  • Include Red/Blue (1/2) galaxy classification (column 8) (See Mohammad et al. 2017)

  • Include Central/Satellite (0/1) flag (column 9)

  • WARNING: the W1 parent mocks are missing a bottom stripe of 36 arcsec width in DEC, compared to the real VIPERS redshift data
