Query tools allow the user to select relevant data tables and to extract and format records matching given criteria. Specific care has been taken for optimizing access to some very large catalogues such as UCAC2, the USNO-B1, or the 2MASS last release. VizieR is a joint effort of CDS (Centre de Données astronomiques de Strasbourg) and ESA-ESRIN (Information Systems Division). VizieR has been available since 1996, and was described in a paper published in A&AS 143, 23 (2000). Note that VizieR does not contain all available online catalogues; some catalogues are not suitable and some less frequently used catalogues have not yet been incorporated into the VizieR database. These last ones can be accessed by FTP from the Astronomer's Bazaar. Simple browsing modes Besides the basic and advanced searches, the existing catalogues may be located through lists organized in several ways: Designations Browse through the list of catalogues in its original hierarchical organisation Acronyms Browse through the known catalog acronyms or abbreviations Favorites Browse through the list of the most frequently queried catalogs Date Browse through the catalogs recently entered into VizieR Images/Spectra Browse through catalogs having associated data, like images, spectra, data cubes (3-D images), time series... The VizieR Mine is a graphical interface to locate the catalogues existing on sky regions The Kohonen Self-Organizing Map groups on nearby locations of a map catalogues having similar contents. VizieR and the Virtual Observatory VizieR can deliver in its advanced mode the results in VOTable, a format which ensures a compatibility the Virtual Observatory tools. VizieR may also in its advanced mode be queried from lists of targets and deliver results in a simple-to-parse tab-separated-values format. Some programmatic interfaces are also available: vizquery is a script which can perform remote queries in all available VizieR modes (individual queries, submission of lists, choice among several output formats); it can run from any Unix/Linux platform Web Services access is also available – though it is inevitably slower than the direct HTTP connection.
