What is ASPIC ?

ASPIC is a portal dedicated to giving access to data and added values from public spectroscopic or spectrophotometric surveys produced and/or hosted at the Centre de données astrophysiques de Marseille (CeSAM), Laboratoire d'Astrophysique de Marseille (LAM), France.
ASPIC builds on the scientific and technical expertise of LAM teams accumulated over the past 15 years on conducting and participating to massive galaxy spectroscopic and spectrophotometric surveys and releasing their data.
The expertise offered by ASPIC aims to address the whole measurement chain, including redshift measurements and reliability assessment, access to spectra and matched ancillary data like multi-band photometry via a dedicated information system.

VUDS survey

Instrument : VLT/VIMOS

The VIMOS Ultra Deep Survey Data Release 1 (DR1) is a public release of all spectroscopic data in the region of overlap between the CANDELS HST imaging survey and VUDS. The data release for 698 objects is distributed over the COSMOS-CANDELS field at around RA(2000)=10h00m28.2s, DEC(2000)=02deg21'36", and the ECDFS around RA(2000)=03h32m30s, DEC(2000)=-27deg48'00".

VVDS survey

Instrument : VLT/VIMOS

The VIMOS VLT Deep Survey (VVDS) is a comprehensive deep galaxy spectroscopic redshift survey conducted by the VIMOS collaboration with the VIMOS multi-slit spectrograph at the ESO-VLT. The VVDS is a combination of 3 nested purely magnitude selected surveys: Wide (17.5 ≤ iAB ≤ 22.5; 8.6 deg²), Deep (17.5 ≤ iAB ≤ 24; 0.6 deg²), Ultra-Deep (23 ≤ iAB ≤ 24.75; 512 arcmin²), with a total of 22434, 12051, 1041 galaxies with measured redshifts in the range 0 < z < 6.7. The final catalog contains 35 016 galaxies and type-I AGN with measured spectroscopic redshifts covering all epochs up to redshift z ~ 6.7, as well as 12 430 Galactic stars, in areas from 0.142 to 8.7 square degrees, and volumes from 0.5 × 106 to 2 × 107 h-3 Mpc3. The release includes the 1D calibrated spectra, measured spectroscopic redshifts and their reliability, as well as all available photometric data matched to the VVDS targets.

zCOSMOS survey

Instrument : VLT/VIMOS

zCOSMOS is an approved Large Program on the ESO VLT. 600 hours of observation are used to carry out a major redshift survey with the VIMOS spectrograph on the COSMOS field to yield spectra for:

  • approximately 28,000 galaxies at 0.2 < z < 1.2 selected to have I_AB < 22.5 at a sampling rate of 70%
  • approximately 12,000 galaxies at 1.2 < z < 3 with B_AB < 25 and
  • chosen by two colour-selection criteria (B-Z) vs. (Z-K) and (U-B) vs. (V-R) at a sampling rate of 70%

GAMA survey

Instrument : AAT/AAOmega

The second GAMA data release (DR2) provides AAT/AAOmega spectra, redshifts and a wealth of ancillary information for 72,225 objects from the first phase of the GAMA survey (2008 - 2010, usually referred to as GAMA I).
