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.


Release of pipeline-processed HAWK-I images as part of the UK in-kind reprocessing project

Published: 18 Aug 2016

All images obtained with the High Acuity Wide field K-band Imager, HAWK-I, from the beginning of regular operations (April 2008) until October 2015 are now published as reduced data (burst mode excluded) via the ESO science archive facility.


Quasars and their absorption lines: a legacy survey of the high-redshift universe with XSHOOTER released

Published: 18 Jul 2016

High-quality echelle spectra of a homogeneous sample of 100 QSOs with redshifts between 3.5 and 4.5, covering the spectral range from 315 to 2500 nm, have been obtained in the course of the ESO observing program 'Quasars and their absorption lines: a legacy survey of the high-redshift universe with VLT/XSHOOTER', lead by PI Sebastien Lopez (program code 189.A-0424). This data set represents the largest spectroscopic survey of high-redshift QSOs with simultaneous rest-frame UV/optical coverage to date, thus enabling a wide range of research topics including the intergalactic medium, active galactic nuclei and cosmological studies.


Release of pipeline-processed MUSE 3D data cubes by the ESO Science Archive Facility

Published: 22 Jun 2016

All spectra obtained with the Integral Field Unit, Multi-Unit Spectroscopic Explorer, MUSE, in the wide field mode, from November 2014 till May 2015 are now published via the ESO archive as reduced data. The MUSE 3D science data cubes1 have their instrumental signature removed, and are astrometrically calibrated, sky- subtracted, wavelength and flux calibrated, using the MUSE pipeline, version muse-1.4 and higher. The data format is a three dimensional FITS image, with two spatial and one spectral axis in the first extension; see the ESO science data products standard (in particular the addendum dedicated to cubes) for a description of the data format and metadata information. Their wavelength scale is in the heliocentric reference system. All 3D data cubes come with error estimates (in the second extension) and a limiting magnitude estimated as 5σ limiting AB magnitude, in terms of the total flux of an unresolved source (i.e. point source). There are a number of files associated at download time to each 3D data cube, the broad – band image, also known as “ white – light ” image, plus graphical (preview) files and the complete pipeline log. The MUSE data collection will grow with time, with new reduced 3D data cubes being added as soon as they are processed. MUSE 3D cubes spectra acquired before November 2014 will also soon be added to the collection.
