VO-compliant publication of Schmidt survey ESO-R of the southern sky digitized with the MAMA microdensitometer at the Observatoire de Paris Image Analysis Centre (CAI).
ESO TAP_CAT: a TAP service to query the astronomical catalogs generated by ESO observers, including the catalogs of the ESO Public Surveys.

Description:
TAP_CAT is the ESO Science Archive service that provides programmatic access onto the
astronomical catalogues produced by the principal investigators of ESO programmes.
The Table Access Protocol (TAP) lets you execute queries against our astronomical catalogues. The queries must adhere to the Astronomical Data Query Language (ADQL, IVOA standard).
Table Upload is not currently supported, though it is foreseen for a next release.
This service provides limited support for spatial queries; only CONTAINS and CIRCLE are supported, as in this example:
CONTAINS(point('', catalog_rightascension, catalog_declination), CIRCLE('', user_defined_rightascension, user_defined_declination, userdefined_radius))= 1.
Please note that CONTAINS(...)=0 is not supported.
A sister service (Catalog Facility: https://www.eso.org/qi) provides a web interface to the same collection of catalogues; the web interface implements a well-defined but limited query model, while instead TAP_CAT provides full ADQL support, allowing users to build their own query constraints using expressions, combining different columns, or using boolean operators (NOT, OR, etc.).
A sibling service (TAP_OBS, endpoint: http://archive.eso.org/tap_obs) exists and can be used to query the raw and reduced data, and the atmospheric measurements taken at the La Silla Paranal Observatory (including APEX).
Estimated distances to 1.33 billion stars in Gaia DR2

Description:
This catalogue provides distances estimates (and uncertainties therein)
for 1.33 billion stars over the whole sky brighter than about G=20.7.
These have been estimated using the parallaxes (and their uncertainties)
from Gaia DR2. A Bayesian procedure was used involving a prior
with a single parameter L(l,b), which varies smoothly with Galactic
longitude and latitude according to a Galaxy model. The posterior is
summarized with a point estimate (usually the mode) and a confidence
interval (usually the 68% highest density interval). The estimation
procedure is described in detail in the `accompanying paper`_,
which also analyses the catalogue content.

This service delivers (most of) the datasets held at
EVN Data Archive. In addition to the default (nonstandard)
way of just appending accrefs to the get access URL, there is also a
very simple datalink service here that, for each dataset, essentially
just gives the dataset itself and possibly a preview. More advanced
datalink services might be available.
Some datasets may be embargoed, in which case the access yields a 403.
Credentials for individual files may be obtained by contacting the
site operators.
The EVN Data Archive's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.
Tables exposed through this endpoint include: main from the evn schema, obscore from the ivoa schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema.
The FAI archives's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.
Tables exposed through this endpoint include: main from the fai_agn schema, main from the geomagnetic_field schema, main from the grb_photometry schema, obscore from the ivoa schema, main from the maksutov_50_telescope schema, main from the neutrons schema, main from the pulsars schema, main from the schmidt_telescope_lc schema, main from the solar_flux schema, data from the spectra_agn_archive schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema.
