I know that specific dataset has been generated from a given Programme ID. I see that Program Id is a selectable item, but the list of available options for X-SHOOTER is way too long to find the right one. Is there a way to type it somewhere in the interface?
The Vista Magellanic Cloud (VMC) Survey DR5.1 is now publicly available on the ESO Archive.
This incremental data release is based on observations acquired between February 2010 and October 2016 of 42 tiles encompassing the whole Small Magellanic Cloud (SMC), the Magellanic Bridge and the Magellanic Stream components of the survey. The total sky coverage is ~40 deg2 in the SMC, ~20 deg2 in the Bridge and ~3 deg2 in the Stream. This release adds reduced and calibrated deep products (co-added tile images and related single band catalogues), together with a multi-band (YJKs) aperture matched, epoch merged source catalogue for more than 14.6 million sources, three multi epoch single band catalogues, a catalogue of variable sources (39406 records) and a PSF photometry catalogue.
The new version of the ESO Science Data Products Standard is now published! This document is the reference for users on how to prepare their data for the submission through Phase 3.
A major effort has been devoted to improve the readability, consistency and clarity of the text and iIt now integrates the information published as separate addenda and in the Phase 3 FAQs.
The PDF version of the standard can be downloaded here.
first of all thank you very much for your awesome work.
I'm new to this data retrieval system and I feel kind of lost in front of it. I'm looking for metallicity data (in particular the [Fe/H] ratio) in the Milky Way bulge: how can I query the various databases for such data?
Thank you very much again!
many thanks for your question.
We suggest you to explore our catalogue facility: https://www.eso.org/qi/ where the content of all catalogues currently in the ESO archive is described. Reading your question, it seems that you may be interested in GAIAESO and AMBRE (but please check thoroughly that this is indeed the case and if there are other surveys that may cover your scientific interest).
To access the content of the catalogue and to download the corresponding data, we provide a variety of options. For instance for GAIAESO you can:
- query the Archive Science Portal for GAIAESO here;
- directly explore the different columns of the catalogue here;
- have access the data programmatically here;
- use the phase3 page dedicated to the collection here.
Please let us know if this satisfy your request and/or if you would like to have further assistance.
Best regards from the Archive Science Group!
We are using the reduced data from the archive to investigate outflows. I would like to check if the detected wings are not related with the instrument profile of the MUSE instrument. To do so, I would like to trace it in the sky emission lines. However, I do not know how access to the intermediate products of the archive reduced data. Please, could you kindly help me with this?
Many thanks in advance
we investigated your question further.
We are assuming that you are interested in the sky cubes (i.e., off-target cubes used to subtract the background generated by the
muse_create_sky recipe). These are processed separately to be used as a sky model for the on-target observations. Such cubes are not available on the Archive.
Yet, these exposures are later treated as actual science exposures and processed as regular on-target data. These latter pipeline-porcessed `sky` cubes are available under the category:
PRODCATG = DATACUBE_FINAL_SKY. However, these are probably not useful for your goal, because they are `sky model` subtracted.
In general, particular products are not available, but there is always a possibility to download the raw data from the ESO Archive and process them. The
muse_create_sky will produce the `sky` cubes (and are not extreme in hardware demanding).
Please let us know if this satisfy your question. In case, you can also take a look to MUSE cubes release description, where the different products available on the Archive are described.
The MUSE Analysis of Gas around Galaxies project (MAGG, ESO programme ID: 197.A-0384, PI: M. Fumagalli) provides the community with high quality VLT/MUSE cubes centered on bright redshift z~3.5 quasars (Lofthouse et al. 2019). These absorbers were discovered in archival high-to-medium resolution spectra of the quasars collected, among others, with UVES and XSHOOTER.
The primary goal of this ESO large programme is to probe the distribution of gas around intermediate redshift galaxies by linking known optically thick absorbers and the galaxies newly discovered by MUSE. This first data release contains 23 MUSE cubes. Each cube results from the combination of a total of 4 hours on source obtained in sub-arcsecond seeing conditions. The dept of this data allows to detect 90% of the point source line emitters brighter than an integrated line flux of 3x10-18erg/s/cm2.
The VISTA Hemisphere Survey (VHS, ESO Programme ID: 79.A-2010, PI R. McMahon) is a wide area - multi band - near infrared survey, which when combined with other VISTA public surveys, will result in the coverage of the whole southern celestial hemisphere (Declination < 0; 20,000 deg2), to a depth 30 times fainter than 2MASS/DENIS in at least two filters (J and Ks), with a minimum exposure time of 60 seconds per filter and a median 5-sigma point source depth of AB = 20.8 and 20.0 in J and Ks filters respectively.
This fifth data release contains a multi-band source catalogue made of 11370 catalogue tiles obtained from Y, J, H and Ks band observations taken over a 8 year period, from the start of the survey in November 2009 to the end of March 2017. There are a total of 1,374,207,485 sources including sources detected in a single waveband. The total sky coverage in at least one waveband is 16,730 deg2. In addition to the multi-band catalogue, DR5 contains the first public ESO release of pawprints, tiles, weight maps and single band source lists for observations obtained in the date range from October 2015 to March 2017. This data release also includes image products of observations taken from April 2015 to September 2015, which were previously released in data release DR4, and are now reprocessed with a more recent version of the CASU pipeline software (version 1.5). More information about the release content can be found in the associated documentation.
The VISTA Kilo-degree Infrared Galaxy Public Survey (VIKING) is a wide area (covering a final area of 1350 sq. deg.), 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.
The sky coverage has maximum overlap with the Kilo-Degree Survey KiDS in the optical bands.
This fourth and final VIKING data release covers all of the highest quality data taken during the survey to its completion and, when combined with the first three releases, includes all fields that met the team’s quality control thresholds in seeing (< 1.3”) and atmospheric transmission (thin cirrus or clearer).
This release contains 935 tiles with coverage in all five VIKING filters, 891 of which have a deep co-add in J, and an additional 44 with at least two filters where the second OB was not executed or one filter in an OB was of poor quality.
The aperture matched multi-band catalogue includes a total of ~100 millions sources (including low-reliability single-band detections), with magnitudes, colours and additional parameters providing information on the nature of each source detection.
More information about this data release is available in the associated release description
The MUSE Library of Stellar Spectra (Ivanov et al. 2019) provides the community with a set of 1D high signal-to-noise spectra with reliable continuum shapes, which populate all major sequences on the Hertzsprung-Russell, with 3-6 bright stars per spectral type.
This first data release contains 35 high-quality MUSE spectra. These stars cover the range of T_eff between 2600 and 33000K, of log(g) between 0.6 and 4.5, and of [Fe/H] from -1.22 to 0.55. The 1D spectra cover the wavelength range from 4800 to 9300 Angstrom, with a resolving power varying from 1750 to 3750, and - given the IFU spectral capabilites of MUSE - are not subject to slit-losses.
VEXAS: the widest and deepest public optical-to-IR photometric and spectroscopic catalogues covering the Southern Hemisphere
First data release of the VISTA EXtension to Auxiliary Surveys (VEXAS)
The VISTA EXtension to Auxiliary Surveys (VEXAS, 'Spiniello & Agnello, 2019, A&A, 630') project aims at providing photometric catalogues with the most uniform spatial coverage, in the multi-wavelength sky for various scientific uses, for example object classification (e.g. quasars, galaxies, and stars; high-z galaxies, white dwarfs), photometric redshifts of large galaxy samples and identification of exotic objects (e.g. extremely red objects and lensed quasars).
This first data release covers the Southern Galactic Hemisphere (SGH) and objects below the Galactic plane, b<-20 deg. It comprises seven cross-matched multi-wavelength photometric catalogues where each object has a match in at least two surveys, plus a reliable photometry in at least three bands. In the current release, the two main extragalactic surveys on the ESO Visible and Infrared Survey Telescope for Astronomy (VISTA) - the VISTA Hemisphere Survey (VHS) and the VISTA Kilo Degree Infrared Galaxy Survey (VIKING) - are cross-matched with several high legacy wide-sky photometric surveys in the optical (the Dark Energy Survey, the Panoramic Survey Telescope & Rapid Response System and SkyMapper Southern Sky Survey), far infrared (the Wide-Infrared Survey Explorer), X-ray (ROSAT All Sky Survey and the XMM-Newton Serendipitous Survey) and radio domain (SUMSS). Finally, the released catalogue includes the cross-matching with spectroscopic data from the Sloan Digital Sky Survey and the 6 degrees Field Galaxy Survey. As of today, the VEXAS catalogues are the widest and deepest public optical-to-IR photometric and spectroscopic catalogues covering the Southern Hemisphere.
