The ADHOC programme (096.C-0730(A) and 097.C-0749(A), PI G. Beccari) is equivalent to an OmegaCAM mini-survey targeting circumstellar discs in nearby Galactic star-forming regions. The scientific goal of this mini-survey is the study of the star formation history of several star-forming regions using deep, wide field, multi-band observations in the optical filters u, g, r, i and Hα, with depth reaching 21 AB mag in r. A total of eight star-forming regions in the Galaxy were observed.
This first data release, published on the ESO phase 3 on February 12th, includes reduced images and single-band sources list for two out of the targeted eight regions, in all the available bands. The two regions covered by science data products in the current release are Gamma Vel (08:09:00 -43:20:00) and Orion A (05:28:00 -07:15:00) for a total of almost 170 sq. deg covered. The products for the additional star-forming regions, including e.g. Lupus, Upper-Sco, Haffner 18, will be made available in future releases.
VANDELS is a deep Public Spectroscopic Survey targeting high-redshift galaxies in the UKIDSS Ultra Deep Survey (UDS) and Chandra Deep Field South (CDFS) survey fields using the VIMOS spectrograph. The goal is to obtain spectra with sufficient signal-to-noise ratio to derive stellar population ages, metallicities and outflows velocities from absorption line studies, allowing a detailed investigation of the physics of galaxies in the early Universe. Within an area of 0.2 deg2, the survey aims at delivering ~2100 high signal-to-noise spectra of star-forming galaxies in the redshift range 1 < z < 7, with 85% of its targets selected to be at z >= 3, and passive galaxies in the redshift range 1 < z < 2.5.
This third data release (DR3) is adding to the available VANDELS collection data taken until December 2017 under the ESO run numbers 194.A-2003(E-T). It consists of 533 1D extreacted spectra provided together with their associated 2D spectra. DR3 provides spectra of 412 additional targets and 121 spectra with increased exposure times with respect to the previous release. In total the VANDELS collection now includes 1774 spectra (897 in CDFS and 877 in UDS), out of which 1607 1D spectra have received 100% of their targeted exposure time.
In addition to the 1D spectra, the release contains a catalogue of derived spectroscopic redshifts and associated reliability flag, among other useful source parameters. More information about the release content can be found in the accompanying documentation.
this is the first time I use the Archive Science Portal...
I would like to select all the spectra observed so far with XSHOOTER, is this possible? And if instead I want to search only for data taken under my program (of which I am the PI)? Even more complicated...if I would like to check the seeing and weather conditions at the telescope when the data were taken?
Thanks a lot,
thanks for your question and for using our ASP...
Yes it is possible to select data taken with a given telescope, you will need to go on the top left corner on your screen and manage the query parameters, as I am showing in the following screenshot.
When clicking on the button, a new menu will pop up:
As you can see, only the first six show up by default but from here you can select a series of other useful searching parameters. , including e.g., the instrument, the Data Collection, The PI, etc.etc.
These will then appear on the left side menu and you will be then able to choose what you wish (e.g. all the X-Shooter spectra or only these belonging to your program).
Concerning your second question, you can do that programmatically ;)
Have a look at this page: http://archive.eso.org/programmatic/#TAP ... here we provide very useful example and demo on how to retrive weather information on a given date or select objects with specific characteristics (like e.g. seeing or FHWM).
I hope this helps!
Please do not hesitate to reply to this message if you need more clarifications.

The fourth data release of the VST Photometric Hα Survey of the Southern Galactic Plane and Bulge (VPHAS+, PI J. E. Drew) includes reduced images and their related source lists taken in the time interval from November 2015 to August 2018, when the survey terminated. By releasing this additional three years of observations, DR4 adds almost 4TB of data to the VPHAS+ collection, effectively doubling the sky area coverage. In total, approximately 2080 deg2 are now covered in all survey filters, which is 92% of the originally planned survey footprint.
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 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 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.
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.
