The VIMOS Public Extragalactic Redshift Survey (VIPERS) is an ongoing Large Programme to map in detail the large-scale distribution of galaxies at 0.5<z<1.2. The project is focused on precisely measuring galaxy clustering and related cosmological quantities, while providing a detailed description of galaxy properties and evolutionary trends, when the Universe was about half its current age. The survey includes a broad legacy for the community, with fairly fast release of the measured redshifts.
VIPERS First Public Data Release
Published: 24 Oct 2013
The first series of scientific results appeared earlier this year (see the overview in The Messenger Guzzo et al. 2013) and Public Data Release 1 (PDR-1) contains the first 57000 redshifts used to produce these analyses. The data correspond to nearly 2/3 of the VIPERS final expected yield and include: a spectroscopic catalogue (IAB<22.5); CFHTLS parent photometric catalogue (five band photometry to IAB=24.0, plus other information); photometric and survey masks, including target sampling rate and redshift measurement success rate; a few reference FITS 1D spectra from stacking thousands of spectra over homogeneous classes.
PDR-1 data are available through the VIPERS site, and can be accessed as a single tarball, containing the full release, or through a user-friendly SQL interface, directly querying the VIPERS database. More details can be found in the survey and data release description papers (Guzzo et al. 2013; Garilli et al. 2013).
