Please be aware that towards the end of 2013, the DSS and other archive services were migrated from the original SOLARIS platform to a modern Linux environment. Some DSS problems have been found and fixed ever since.

In case you discover some new issues with the DSS service (whether via the web, via the DSS batch tool, or via the Skycat interface), we would like to invite you to please send your feedback to: archive@eso.org mentioning DSS in the subject. 

Of course, you can use the same email address for any other issue you might have with other ESO archive services.

Thanks in advance for your  collaboration,

The collection of pipeline-processed high-resolution spectral data obtained with the Ultraviolet and Visual Echelle Spectrograph (UVES) has been significantly extended, now also including the observations that make use of the image slicers in order to optimize the observing efficiency during sub-optimal seeing conditions. In addition to the UVES data announced on 24 October 2013, over 10,000 individual spectra, which have been acquired in the period between 2003 and 2013, are now available from the ESO Science Archive Facility. The data consist of extracted wavelength- and, whenever possible, flux-calibrated 1-dimensional spectra in tabular format following the established ESO science data products standard.

VIKING belongs to the suite of six public surveys being conducted at ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA). The VISTA Kilo-degree Infrared Galaxy Survey (VIKING) is a wide area (eventually ~1500 sq.degrees), intermediate-depth (5-sigma detection limit J~21 on Vega system) near-infrared imaging survey, in the five broadband filters Z, Y, J, H, Ks.

Data products resulting from the first release of the Gaia-ESO Public Spectroscopic Survey are now available via the dedicated Phase 3 query interface at the ESO Science Archive Facility.

Data products resulting from the first release of the ESO/VST Public Survey ATLAS are now available via the dedicated Phase 3 query interface at the ESO Science Archive Facility.

The ESO archive now provides access to reduced scientific data obtained with the UVES spectrograph mounted on the VLT.

Data products resulting from the first release of the ESO/VST Public Survey VPHAS+ are now available via the dedicated Phase 3 query interface at the ESO Science Archive Facility.

This data release covers the first 9 months of data-taking in which a tenth of the survey footprint was observed to desired quality. These first pointings have favoured the Galactic equator and some well-known open clusters of interest to the Gaia-ESO Survey. Reduced images and unstacked single-band source lists are provided. The total data volume of this data release is 749 GB.

Following the news of the 3rd of April, the media production service is now re-enabled. It is accessible via the dataportal facility which the user can reach after submitting a request using the "Request marked datasets" button. It now allows users to either instantaneously download the data they requested or request for their data to be copied onto a USB disk. The latter option is only available for requests totaling more than 400 GB. The USB disks are expected to be sent back to ESO within 2 weeks after reception.

Stellar radial velocities, atmospheric parameters (effective temperature, surface gravity, mean metallicity [M/H]) and enrichment in alpha-elements ([alpha/Fe]) resulting from the automatic analysis of 21551 FEROS spectra from the ESO data archive with the MATISSE algorithm have been released. Go to the ESO Catalogue Facility(*) for data download and further information.

Data products resulting from ESO programme ID 60.A-­9284(H) as part of the first HAWK-­I science verification  are now available via the dedicated Phase 3 query interface at the ESO Science Archive Facility.

This data release consists of a mosaic of four pointings in two filters J and Ks, with the center of the X-­ray luminous galaxy cluster XMMU J2235.3-­2557 imaged in the four extreme corners of the HAWK-I detector mosaic. The deep image covers 13' by 13' on the sky with a pixel scale of 0.1065''. The image quality varies from 0.3'' to 0.7'' depending on filter and location.
