Release of GIRAFFE Medusa science data products

Published: 12 May 2015

All spectra obtained with the spectrograph FLAMES/GIRAFFE in the MEDUSA mode from June 2005 till December 2014 are now published via the ESO archive as reduced data. The extracted, wavelength calibrated, one-dimensional spectra are in tabular FITS format, see the ESO science data products standard for a description of the data format and metadata information. Their wavelength scale is in the heliocentric reference system. All 1D-spectra come with error estimates and signal-to-noise ratio per wavelength bin. There are a number of files associated at download time to each spectrum, including sky spectra when available. The GIRAFFE_MEDUSA data collection will grow with time, with new reduced spectra being added with monthly cadence. FLAMES GIRAFFE spectra acquired before June 2005 will also soon be added to the collection. The 1D spectra tagged "GIRAFFE_MEDUSA", can be queried and downloaded using the Phase 3 generic query form that provides access to all Phase 3 data or the Phase 3 query form dedicated to spectral data with query parameters suited to harvest spectral data.


IRAF support for ESO tabular FITS format 1D spectra

Published: 31 Mar 2015

ESO one-dimensional (1D) spectra in tabular FITS format can now be displayed and processed with IRAF using the external package SPTABLE, thanks to a close collaboration between ESO and the IRAF developers. The popular IRAF ONEDSPEC package, including SPLOT, and the IRAF RV package are now able to process the 1D spectra from the spectroscopic ESO Public Surveys (PESSTO and Gaia-ESO), Large Programmes (ESSENCE, GOODS FORS2+VIMOS, and zCOSMOS) and internal data products (UVES ECHELLE, XSHOOTER ECHELLE, HARPS, soon GIRAFFE, etc.).


New data of the VISTA Deep Extragalactic Observations (VIDEO) Survey in the ELAIS-S1 field released

Published: 26 Mar 2015

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).


New imaging data for the VISTA Variables in the Via Lactea Survey released

Published: 09 Mar 2015

The VISTA Variables in the Via Lactea Survey (VVV) is a wide area, near-infrared, multi-epoch imaging survey of the Milky Way bulge and disk. The initial survey in the five broadband filters Z, Y, J, H, Ks for a total sky coverage of 540 sq deg, is followed by extensive multi-epoch observations in the Ks band.

New catalogue release from the VISTA Magellanic Survey published

Published: 16 Feb 2015

The VISTA Magellanic Survey is now publishing the a new catalogue release based on the Point Spread Function (PSF) photometry in three bands Y, J and Ks,


New releases of images and catalogues in the optical and near-infrared bands resulting from the VISTA-VIKING and VST-KiDS surveys

Published: 06 Feb 2015

The VISTA Kilo-degree Infrared Galaxy Survey (VIKING) - one of the public surveys being conducted at ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA) - is a wide area (final coverage: 1500 deg2), intermediate depth, near infrared imaging survey at high galatic latitudes, in five broadband filters Z, Y, J, H, Ks. Science goals include high-redshift quasars, extreme brown dwarfs, as well as multiwavelength coverage and identifications for a range of other imaging surveys, notably VST-KiDS and Herschel-ATLAS.


Second release of photometric catalogue data resulting from the VISTA Magellanic Survey

Published: 09 Jan 2015

The VISTA Magellanic Survey (VMC) - one of the six public surveys being conducted at ESO’s Visible and Infrared Survey Telescope for Astronomy - aims at the determination of the spatially resolved star formation history and the three-dimensional geometry of the Magellanic system. The sensitivity is designed to reach sources below the oldest main-sequence turn off point of the stellar population and the multi-epochs to measure accurate Ks mean magnitudes for pulsating variable stars, e.g. RR Lyrae stars and Cepheids.
