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: http://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: http://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).
