This schema contains data re-published from the official
Gaia mirrors (such as ivo://uni-heidelberg.de/gaia/tap) either to
support combining its data with local tables (the various Xlite tables)
or to make the data more accessible to VO clients (e.g., epoch fluxes).
Other Gaia-related data is found in, among others, the gdr3mock,
gdr3spec, gedr3auto, gedr3dist, gedr3mock, and gedr3spur schemas.
This service returns the most important Gaia DR3 gaia_source columns
together with robust geometric and photogeometric distances for the
~1.47 billion objects in Bailer-Jones et al's distance catalogue.
This is a re-publication the Gaia DR3 RP/BP spectra in the IVOA Spectral
Data Model. It presents the continous spectra in sampled form, using a
Monte Carlo scheme to decorrelate errors, elaborated in this resource's
reference URL. The underlying tables are also available for querying
through TAP, which opens some powerful methods for mass-analysing the data.
High-Resolution Very Large Array Imaging of Sloan Digital Sky Survey
Stripe 82 at 1.4 GHz

The GAVO DC team
Description:
This is a high-resolution radio survey of the Sloan Digital Sky Survey
(SDSS) Southern Equatorial Stripe, a.k.a. Stripe 82. This 1.4 GHz survey
was conducted with the Very Large Array (VLA) primarily in the
A-configuration, with supplemental B-configuration data to increase
sensitivity to extended structure. The survey has an angular resolution
of 1.''8 and achieves a median rms noise of 52 μJy per beam over 92 deg^2.
The catalog contains 17,969 isolated radio components, for an overall
source density of ∼195 sources/deg^2. See also J.A. Hodge et al,
:bibcode:`2011AJ....142....3H` .
This services provides 1D spectra from DR5 of LAMOST (Large Sky Area
Multi-Object Fiber Spectroscopic Telescope) through SSAP;
data is served both in VO-standard SDM and, via datalink, the original
SDSS-inspired FITS described in
http://dr5.lamost.org/doc/data-production-description .
The 2MASS Point Source Catalogue, short a couple of exotic fields. We
provide this data mainly for matching with other catalogs within our
TAP service.
MAST SkyMapper Southern Survey Data Release 4 (SMSS DR4)
Short Name:
MAST SkyMapper

Space Telescope Science Institute Archive
Description:
MAST hosts a copy of the SkyMapper DR4 catalog.
SMSS DR4 contains optical photometry in the 6 SkyMapper filters (u,v,g,r,i,z) for ~700 million astrophysical sources over 26,000 sq.deg, ranging from the South Celestial Pole to Dec=+16 degrees for objects with data in all bands, and some sources as far North as +29 degrees. The photometry is drawn from over 15 billion measurements made from more than 400,000 images acquired by the 1.3m SkyMapper telescope between March 2014 and September 2021. The typical 10-sigma depths for each field range between 18.5 and 20.5 ABmag, depending on the filter, but certain sky regions include longer exposures that reach as deep as 22 ABmag.
Compared to previous SkyMapper data releases, DR4 includes significant enhancements in data processing, most notably a new photometric calibration anchored to synthetic photometry from Gaia low-resolution spectroscopy, which resolves reddening- and spatial-trends identified in previous releases, especially in the bluest filters, u and v.
A large number of other photometric and spectroscopic surveys have been cross-matched to the dr4.master table of objects, to facilitate various scientific investigations.
MWSC presents a list of 3006 Milky Way Stellar Clusters (MWSC), found
in the 2MAst (2MASS with Astrometry) catalogue. The target list was
compiled on the basis of present-day lists of open, globular and
candidate clusters. For confirmed clusters we determined a homogeneous
set of astrophysical parameters such as membership, angular radii of
the main morphological parts, mean cluster proper motions, distances,
reddenings, ages, tidal parameters, and sometimes radial velocities.
