The catalogues are based on data from the VISTA Variables in the Via Lactea (<a adhocenable="false" href="https://vvvsurvey.org/">VVV</a>) Survey and its extension, VVVX, and offer unprecedented precision in astrometric and depth.</p> <p>The VIRAC2 catalogues include positional data, proper motions, parallaxes, and near-infrared time series for over 545 million stars across approximately 560 square degrees of the southern sky, using data from 2010 to 2019 in ZYJHKs bands. They use Gaia DR3 as an external astrometric reference catalogue, and hence astrometry is on an absolute reference frame, in contrast to VIRAC v1. A global photometric calibration algorithm has been adopted, using 2MASS as an external photometric reference catalogue, with an additional non-astrophysical noise reduction stage.</p> <p>The catalogues reach magnitudes as faint as Ks ≈ 17.5, approximately 1 mag deeper than VIRACv1, and achieve proper motion uncertainties as low as 0.37 mas/yr for bright sources. Parallax measurements are available for all stars observed in at least ten epochs.</p> <p>The release includes five tables:</p> <ol> <li>VVVX_VIRAC_V2_SOURCES</li> <li>VVVX_VIRAC_V2_LC</li> <li>VVVX_VIRAC_V2_REJECTED_SOURCES</li> <li>VVVX_VIRAC_V2_REJECTED_LC</li> <li>VVVX_VIRAC_V2_OBS.</li> </ol> <p>The source tables I and III contain the aggregate source data (e.g. positions, proper motions, mean photometry), tables II and IV are the time series data (photometric and astrometric), and table (v) contains observation-related information (e.g. image filename, seeing). The content has been split into main and rejected selections. The raw catalogue contained junk rows for a variety of reasons (e.g. duplicates, erroneous detections in the wings of the PSFs of bright stars, etc.), and these were separated into the rejected tables which are included since some interesting sources (e.g. photometric transients) can have been flagged as ‘rejected’.</p> <p>Together with the catalogues, complementary data, including over 24,000 pawprint images, source tables, and confidence maps, are also provided.

The sixth and lastUltraVISTA data release, “DR6” or “Legacy”, 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 release is based on the observations carried out from December 2009 to March 2023, corresponding to 99,845 individual images. The observations obtained since the DR5 release are mostly in the Y -band “deep” stripes in order to bring them to the same depth as the previously observed “ultra-deep” stripes. Thus, in this release, the depth is nearly uniform over the full field for the broad-band Y JHKs filters. This release also uses GTO data obtained in 2010 in the J and the NB118 filters in the “deep” stripes.</p> <p>The total exposure time contributing to this release is 2290 hours, and the total survey area is close to 1.9 square degrees.

Dunlop, M. Franx, J. Fynbo, O. LeFèvre, Programme ID 179.A-2005, 198.A-2003) is an ultra-deep near-infrared ESO Public Survey targeting the central region of the COSMOS field. This public survey started in April 2010 and has been completed during the VISTA Public Survey Cycle II in 2022.</p> <p>This new release (DR4.1) contains two independent multi-wavelength photometric catalogues, computed using different techniques. The CLASSIC catalogue is generated using an aperture photometric measurement method as that adopted in the previous COSMOS2015 catalogue. The second catalogue, labelled FARMER, is created using a new profile-fitting photometric tool which the UltraVISTA team developed. The FARMER catalogue uses a source list derived independently from the CLASSIC one. The data present in the previous COSMOS2015 catalogue have been reprocessed to take advantage of the improved astrometry from the Gaia reference catalogue.</p> <p>About 1 million sources are measured with all available broad-band data, with both methods. Photometric redshifts and physical parameters are computed for both catalogues using LePhare (Arnouts et al. 2002; Ilbert et al. 2006) and EAZY (Brammer et al. 2008). At i < 21, sources have sub-percent photometric redshift precision and even the faintest sources at 25 < i < 27 reach a photometric redshift accuracy of 5 %.</p> <p>The principal improvements in COSMOS2020 catalogues compared to previous COSMOS2015 catalogue are the significantly deeper optical and near-infrared images from the Subaru-HSC and VISTA/VIRCAM imaging surveys. In addition, this release contains the definitive reprocessing of all Spitzer data ever taken on COSMOS.</p> <p>More details about the release content can be found in the accompanying <a adhocenable="false" href="http://www.eso.org/rm/api/v1/public/releaseDescriptions/195">Phase3 release documentation</a> and in the dedicated paper <a adhocenable="false" href="https://iopscience.iop.org/article/10.3847/1538-4365/ac3078">Weaver et al. 2022</a>.</p> <p>The catalogues are available via the ESO archive <a adhocenable="false" href="https://archive.eso.org/scienceportal/home?data_collection=UltraVISTA&publ_date=2022-06-30">Science Portal</a> or <a adhocenable="false" href="http://archive.eso.org/programmatic/#TAP?e=1&f=text&m=200&q=--SELECT%20schema_name%2C%20table_name%20from%20TAP_SCHEMA.tables%20where%20table_name%20like%20'COSMOS2020_%25'%0A%0ASELECT%20top%20100%20*%20from%20safcat.COSMOS2020_CLASSIC_V2&">programmatically</a>.</p> </div> <div class="richtext text parbase section"> <p><span class="orange1"><b><a id="gaiaeso_dr5"></a>16 May 2022</b></span></p> <p><b>Fifth Gaia-ESO data release: the catalogue with the astrophysical parameters for ~115000 stars</b></p> <p><a adhocenable="false" href="https://www.gaia-eso.eu/">Gaia-ESO</a> is an ESO Public Spectroscopic Survey (under ESO Programme IDs: 188.B-3002, 193.B-0936, 197.B-1074; PIs: Gerry Gilmore & Sofia Randich) carried out with GIRAFFE and UVES on the VLT between 2012 and 2018.

The instrument is located at the VLT UT1 telescope and has 24 image slicer Integral Field Units (IFUs) that can be placed independently in the patrol field of 7.2 arcmin diameter. Each IFU has 14 slices with 14 spatial pixels along each slice and a field-of-view of 2’’.8x2’’.8 which gives a spatial resolution of 0’’.2. Spectral resolving power depends on the grating and is between 2000 and 4200. This initial release consists of observations from October 2013 (i.e. start of operations) until February 2020. The content of the release grows with time as new data are being acquired and processed.</p> <p>Data have been reduced using the KMOS pipeline version 2.7.3 or higher. Data reduction is executed first for each IFU containing an object. It includes sky subtraction, flat fielding, wavelength calibration, flux calibration, and cube reconstruction. Telluric absorption features in the individual cube spectra are corrected. For this, an atmospheric model is fit to the closest-in-time telluric standard star measurement using the <a adhocenable="false" href="https://www.eso.org/sci/software/pipelines/skytools/molecfit">molecfit</a> software. This model is scaled with the airmass difference between science observation and standard star measurement and applied to the extracted spectra. Flux calibration is applied using the zero-point measurement from the same standard star, without assessment of the photometric conditions. Note that all standard stars serve both as telluric and as photometric standards.</p> <p>The KMOS data collection is current to March 2020, when observations were halted because of the Coronavirus-induced lockdown. It will grow again with time as observations will resume, with future processing on a roughly monthly cadence.

The associated multi-band catalogue includes a total of 46 million sources.</p> <p>The Kilo-Degree Survey (KiDS) - one of public surveys being conducted with the VLT Survey Telescope (VST) - will image 1500 sq. degrees in four filters (u, g, r, i). It is designed to be a weak lensing shear tomography survey, but also to map the large-scale matter distribution in the universe and constrain the equation of state of Dark Energy. Secondary science cases include galaxy evolution to Milky Way structure and from the detection of white dwarfs to high-redshift quasars.</p> <p>This second data release consists of coadded images, weight maps, masks and single-band source lists for 98 tiles that were completed between October 2012 and September 2013.
