New data releases on the Archive Science Portal

Archive Science Group 5 months ago 0

Exciting day today at ESO with two new data releases!

Fourth data release of data from the VST ATLAS Public Survey

The ESO Public Survey ATLAS with VST is targeting 4500 square degrees of the southern sky in u,g,r,i,z to depths comparable to those of the Sloan Digital Sky Survey SDSS (r~22). Its wide wavelength coverage, from the u- to z-band complements the VISTA VHS and VIKING Surveys in YJHK bands.

The new stacked reduced images and associated source lists, for the period Oct 2014 to July 2017 and reprocessed stacked reduced images up to 2014 are available from the ESO Archive Science Portal.  Moreover the band-merged catalogue data, containing 155 million records, can be queried via the dedicated Catalog Interface.
More details about the release content can be found in the associated Phase 3 data release description.

Second data release of the MUSE cubes of the Large Programme 'Dissecting GAs Stripping Phenomena in galaxies (GASP, 196.B-0578, PI: B.Poggianti - http://web.oapd.inaf.it/gasp/). 

The scientific goal of this large programme is to study galaxies at z = 0.04-0.07 in different environments.
For each target galaxy, the released science data products are the reduced and combined MUSE 3D data cubes that can be queried and downloaded using the Archive Science Portal.

The 3D science data cubes come with additional associated products. These products are extracted 1D spectra plus associated maps of the emission-line fluxes for the Halpha and Hbeta emission, the Halpha 2D line-of-sight velocity field, the average star formation rate in four age bins, as well as luminosity-weighted stellar age and stellar mass density maps.

A more detailed description of the Large Program and a comprehensive data documentation can be found here.

The first release of the UVES Spectral Quasar Absorption Database (SQUAD) is online!

Archive Science Group 7 months ago 0


 The UVES SQUAD DR1 comprises fully reduced, continuum-fitted high-resolution spectra of quasars with redshifts z = 0–5, with the primary goal of enabling statistical studies of large quasar and absorber samples at high resolution. DR1 includes 467 quasar spectra from the Ultraviolet and Visual Echelle Spectrograph (UVES) on the ESO-VLT. These quasars have at least one exposure in the ESO UVES archive (longer than 100 sec) that was observed before 30th June 2008. All exposures longer than 100 sec observed before 17th November 2016 for these quasars were then included in the final, combined spectra in DR1. In total, 3088 exposures were selected and successfully processed, with a total exposure time of 10 million seconds (2803 hrs; an average of 5.9 hrs per quasar).

The spectra are available from the ESO Science Portal or Programmatically. More details about the release content can be found in the associated Phase 3 data release description.

Fourth release of UltraVISTA Public Survey data

Archive Science Group 7 months ago updated 7 months ago 1


The fourth release of the ultra-deep near-infrared survey of the central region of the COSMOS field is now publicly available from the ESO Archive Science Portal or the Programmatic Access service. 

This fourth UltraVISTA data release, based on observations carried out from 4 December 2009 to 29 June 2016, comprises stacked images in YJHKs and NB118 narrow-band filters, as well as single-band and dual-mode source lists. The data release also contains a five-band merged catalogue, created from the individual Ks-selected source lists.  The total exposure time contributing to this release is 1287.5 hours, and the total survey area is close to 1.9 sq.deg. 

More details about the release content can be found in the associated Phase 3data release description

First data release from VISIONS - VISTA Star Formation Atlas - Public Survey

Archive Science Group 7 months ago updated 7 months ago 1

VISIONS is a sub-arcsec NIR atlas of the nearby (d < 500 pc) star forming complexes accessible from the southern hemisphere. The atlas will contain tens of thousands of young starts (0.1 to 10 Myr), will be sensitive to objects down to few Jupiter masses and reach spatial resolutions of 100-250 AU.

This first release includes excellent quality J, H and Ks band observations of the dense field of the Ophiuchus star-forming region. More details about the release content can be found in the accompanying Phase 3 data release documentation.


Images, confidence maps and source lists, together with band-merged catalogues associated to each individual tile, are accessible via the Science Portal or via the Programmatic Access Service

KIDS DR4 published on February 28th

Archive Science Group 7 months ago updated 7 months ago 1

New data from the Kilo-Degree Survey 
The fourth data release covers 1107 square-degrees and more than doubles the sky area covered by the previous three releases combined. For the first time, it includes photometry from the partner VIKING ESO public imaging survey on VISTA. For each of the 1006 square-degree survey tiles the data release includes calibrated stacked images in u,g,r and i filters, their corresponding weights and masks, and single-band source lists extracted from the stacks. Furthermore, the multi-band ugriZYJHKs photometric  catalogue covers 1006 square degree survey tiles, with PSF-homogenised and aperture-matched photometry and photometric redshift estimates. 

More details about the release content can be found in the associated Phase 3 data release description

The products are available via the ESO Archive Science Portal or the Programmatic Access service.
The catalogue records can be queried programmatically or via the dedicated Catalog Interface.

First release of pipeline-processed APEX data: the Boomerang nebula

Archive Science Group 9 months ago updated 8 months ago 1

We are happy to announce that the ESO APEX science operations team have now started the processing of public APEX archival data using standard calibrations.

This initial release by the APEX team consists of a flux map from the LABOCA observations of the Boomerang Nebula. These observations were taken under the ESO programme 092.F-9305(A), during the second half of 2013. The planetary nebula shows a unique high speed wind and mass expansion features, resulting into temperatures that are even colder than the CMB radiation. The released flux map at 870 um provides the opportunity to study the dust around the envelope and the grain size distribution of this planetary nebula. The data are combined and calibrated via a standard process using the BoA software for bolometer data reduction.

The products are available via the ESO Science Portal or the Programmatic Access service. More details about the release content can be found in the associated Phase 3 data release description.

In-house reprocessed VIMOS images

Archive Science Group 9 months ago updated 8 months ago 1

We are happy to announce that all VIMOS imaging science observations from 2003 until the end of VIMOS operations in March 2018 have now been processed by ESO and are added to the previous VIMOS imaging data release. 

The science products are published via the ESO Science Portal and they can also be downloaded via programmatic access.

More details about data processing, the content of the source lists, data quality, astrometric and photometric calibrations are available in the associated Phase 3 data release description.
