Release of the UltraVISTA/COSMOS2015 catalogue (Laigle et al. 2016)

Published: 20 Dec 2016

The COSMOS2015 catalogue contains precise photometric redshifts and stellar masses for more than half a million objects over the 2 deg2 COSMOS field. Including YJHKs DR2 images from the UltraVISTA ultra-deep near-infrared survey, Y-band from Subaru/Hyper-Suprime-Cam and infrared data from SPLASH Spitzer legacy program, this near-infrared selected catalogue is highly optimised for the study of galaxy evolution and environments in the early Universe.


New spectra and images of the PESSTO public survey released in December 2016

Published: 19 Dec 2016

A new release of the Public ESO Spectroscopic Survey for Transient Objects (PESSTO) is available. This release adds 1350 spectra and 383 images to the previously published PESSTO data. All the EFOSC (2851) and SOFI (226) spectra and all the reduced SOFI images (775) obtained during the first four years (April 2012-April 2016) of PESSTO operations, and covering 1168 distinct transient objects, are available via the Phase 3 query interface at the ESO Science Archive Facility.

The PESSTO public survey data release (DR3) is accompanied by a comprehensive description of the spectra and images.

New versions of the transient and lightcurve catalogs will become available in early 2017.

Instructions on how to read or display data in the ESO/SDP tabular data format can be found in the 1D spectrum data format help page.


Release of spectra and catalogue from the VIMOS Public Extragalactic Redshift Survey (VIPERS)

Published: 15 Dec 2016

More than ninety thousands spectra and a redshift catalogue are now released from the VIMOS Public Extragalactic Redshift Survey (VIPERS), carried out under the ESO Large Program 182.A-0886, PI L. Guzzo. This is the largest galaxy redshift survey conducted so far at ESO Paranal facilities.


Flux calibration issue for the XSHOOTER UVB data products

Published: 29 Nov 2016

We recently found an issue with the flux calibration of the XSHOOTER data products, for the blue (UVB) arm. The calibration is done with master response curves, which however show significant deviations (above the ±10% limit quoted in the release description) from the proper nightly response curves. This is true since about April 2015. There are also two sudden changes introducing a spectral artefact at λ=365nm, approximately the Balmer discontinuity, around dates 2015-07-30 and 2016-02-10.


FEROS Pipeline Processed Data Available Through Phase 3

Published: 07 Nov 2016

Pipeline processed FEROS echelle data, covering the period November 2003 to the present, are now available as Science Data Products via the Phase 3 main and spectral query forms. The data consist of 1D spectra in the ESO/SDP format and the tar files containing output of the pipeline.


Third public release of the Kilo-Degree Survey (KiDS) now available

Published: 10 Oct 2016

KiDS is one of the ESO Public Surveys carried out with OmegaCAM at the VST. Once complete, it will observe 1500 square degrees in four filters (u, g, r, i). Born to be a weak lensing shear tomography survey, it will also map the large-scale matter distribution in the universe and constrain the equation of state of Dark Energy. Its secondary science cases include galaxy evolution to Milky Way structure and from the detection of white dwarfs to high-redshift quasars.

New data of the VISTA Deep Extragalactic Observations (VIDEO) Survey in the ELAIS-S1, CDFS, and XMM-LSS fields released

Published: 29 Sep 2016

VIDEO is a deep near-infrared survey which targets ~12 square degrees over the ELAIS-S1, XMMLSS, and ECDFS extragalactic fields. VIDEO belongs to the suite of six public surveys being conducted at ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA).


Release of Proxima Centauri HARPS science spectra

Published: 07 Sep 2016

The science 1-D spectra products from the HARPS observations of the ESO programme 096.C-0082, P.I. Guillem Anglada, from January to March 2016, are now available from the ESO Science Archive Facility. The results from the analysis of these spectra are published in the paper entitled “A terrestrial planet candidate in a temperate orbit around Proxima Centauri”, by G. Anglada-Escudé et al., in Nature.


The first data release of the Large Early Galaxy Census (LEGA-C) survey now available via the ESO Science Archive Facility

Published: 31 Aug 2016

The LEGA-C ESO Public Spectroscopic Survey is now releasing science products from the first year of observations. LEGA-C started in December 2014 and observations are planned to be completed by mid 2018, with early data releases of the spectra and value-added products. More information on the survey design, sample selection, observing strategy, data reduction, are available at this link:http://adsabs.harvard.edu/abs/2016ApJS..223...29V.
