ESASky is a science-driven discovery portal providing full access to the entire sky as observed with all ESA Space astronomy missions. This service provides access to catalogues, observations, and spectra hosted at the ESAC Science Data Centre.
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).
ESO TAP_OBS: a TAP service to browse and access raw and reduced data, and to query the ambient measurements, of the La Silla Paranal Observatory.

Description:
TAP_OBS is the ESO Science Archive TAP endpoint for observations (raw and reduced data) and ambient measurements (atmospheric seeing, turbulence, water vapour, relative humidity, air pressure, etc.) taken at the La Silla Paranal Observatory, including the Chajnantor (APEX) data.
The Table Access Protocol (TAP) lets you execute queries against our database tables, and inspect various metadata. Table Upload is not currently supported, though it is foreseen for a next release.
The IVOA ObsCore standard service is also provided (table name: ivoa.ObsCore), but currently only for reduced data.
Other tables exposed are the dbo.raw describing all the LPO observations, the ambient tables (in the asm schema), plus the provenance table to close the loop between the raw and the reduced data, but also to describe the relationships between reduced data (e.g. a source table originating from a reduced image, etc.).
A sibling service (TAP_CAT, endpoint: https://archive.eso.org/tap_cat) exists and can be used to query the astronomical catalogs produced by the principal investigators of ESO programmes (ESO public surveys included).
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.
