This data release provides deep 3D data cubes obtained with the Multi-Unit Spectroscopic Explorer (MUSE) integral field unit, in the wide field mode, from data acquired starting from June - August 2014, plus the initial two periods of MUSE operations, P94 and P95 (September 2014 until September 2015). These deep cubes are now published via the ESO Science Archive as reduced data.

As part of the agreement between ESO and IPAG (Institut de Planétologie et d'Astrophysique de Grenoble) to offer the PIONIER interferometric instrument attached to the VLTI in service and visitor mode for periods 96 to 99, IPAG has committed to process the raw data and deliver calibrated visibility data (squared visibility amplitudes and closure phases) to the ESO archive.

The VISTA Magellanic Survey (VMC) led by principal investigator M.-R. Cioni aims at the determination of the spatially resolved star formation history and the three-dimensional geometry of the Magellanic system. VMC has been designed to reach sources below the oldest main-sequence turn off point of the stellar population with multi-epoch coverage to measure accurate Ks mean magnitudes for pulsating variable stars, e.g. RR Lyrae stars and Cepheids.

The ESO/VST Public Survey ATLAS is targeting 4500 square degrees of the Southern sky in five filters u,g,r,i,z to depths comparable to those of the SDSS. Its wide wavelength coverage, from the u to the z bands complements the VISTA VHS and VIKING Surveys in the YJHK bands. This survey is relevant for cosmology studies, but it can also be exploited for many other  branches of extragalactic and Galactic astronomy studies.

The VVV Survey data release DR4 provides the VISTA tile images and source lists in the ZYJHKs filters, processed by the Cambridge Astronomical Survey Unit (CASU), for a total sky coverage of 560 sq.deg.

The Kilo-Degree Survey (KiDS) is an ESO public survey carried out at the VLT Survey Telescope (VST) with the OmegaCAM camera. It is designed to be a weak lensing shear tomography survey and its core science drivers are to map the large scale matter distribution in the universe and constrain the equation of state of Dark Energy. The catalogue that is now released is the first weak lensing shear dataset from KiDS with which these questions have been addressed.

The COSMOS2015 catalogue contains precise photometric redshifts and stellar masses for more than half a million objects over the 2 deg² COSMOS field. Including YJHKs DR2 images from the UltraVISTA ultra-deep near-infrared survey, Y-band from Subaru/Hyper-Suprime-Cam and infrared data from SPLASH Spitzer legacy program, this near-infrared selected catalogue is highly optimised for the study of galaxy evolution and environments in the early Universe.

A new release of the Public ESO Spectroscopic Survey for Transient Objects (PESSTO) is available. This release adds 1350 spectra and 383 images to the previously published PESSTO data. All the EFOSC (2851) and SOFI (226) spectra and all the reduced SOFI images (775) obtained during the first four years (April 2012-April 2016) of PESSTO operations, and covering 1168 distinct transient objects, are available via the Phase 3 query interface at the ESO Science Archive Facility.

The PESSTO public survey data release (DR3) is accompanied by a comprehensive description of the spectra and images.

New versions of the transient and lightcurve catalogs will become available in early 2017.

Instructions on how to read or display data in the ESO/SDP tabular data format can be found in the 1D spectrum data format help page.

More than ninety thousands spectra and a redshift catalogue are now released from the VIMOS Public Extragalactic Redshift Survey (VIPERS), carried out under the ESO Large Program 182.A-0886, PI L. Guzzo. This is the largest galaxy redshift survey conducted so far at ESO Paranal facilities.

We recently found an issue with the flux calibration of the XSHOOTER data products, for the blue (UVB) arm. The calibration is done with master response curves, which however show significant deviations (above the ±10% limit quoted in the release description) from the proper nightly response curves. This is true since about April 2015. There are also two sudden changes introducing a spectral artefact at λ=365nm, approximately the Balmer discontinuity, around dates 2015-07-30 and 2016-02-10.
