glots.columnsTable InfoA table of columns within the tables listed in glots.tables. The global TAP schema collects information on tables and columns from known TAP servers. This facilitates locating queriable data by physics (via UCD) or keywords (via description).
glots.servicesTable InfoA table of TAP services harvested from the registry (and some spoon-fed). The global TAP schema collects information on tables and columns from known TAP servers. This facilitates locating queriable data by physics (via UCD) or keywords (via description).
glots.tablesTable InfoA table of tables accesible through the TAP services known to glots.services. The global TAP schema collects information on tables and columns from known TAP servers. This facilitates locating queriable data by physics (via UCD) or keywords (via description).
ivoa.emptyobscoreTable InfoAn empty table having all columns of the obscore table. Useful internally, and sometimes for tricky queries.Definition and support code for the ObsCore data model and table.
ivoa.ObsCoreTable InfoThe IVOA-defined obscore table, containing generic metadata for datasets within this datacenter.Definition and support code for the ObsCore data model and table.

obscode.dataTable Info List of Observatory Codes assigned by the Minor Planet Center (MPC). The codes are used in cataloguing astrometric observations of small bodies in the solar system. A code is unique for a certain location and consists of three digits or one letter and two digits. In this representation, we give the observatory code, the geocentric coordinates, and the observatory designation. List of Observatory Codes assigned by the Minor Planet Center (MPC).

ppmxl.mainTable Info PPMXL is a catalog of positions, proper motions, 2MASS- and optical photometry of 900 million stars and galaxies, aiming to be complete down to about V=20 full-sky. It is the result of a re-reduction of USNO-B1 together with 2MASS to the ICRS as represented by PPMX.

pul.pulsarTable InfoThe pulsar timing data were obtained with the Nanshan 25M radio telescope. Our observations, which commenced in January 2000, have been made using a dual-channel room-temperature receiver with a bandwidth of 320 MHz centered at 1540 MHz before June 2002. The de-dispersion was provided by a 2X128X2.5 MHz analog filter-bank. The format of the AFB data is "Timer". A cryogenic receiver was mounted in July 2002, which increases the sensitivity to 0.5 mJy. In January 2010, a digital filter-bank (DFB) system came into operation. The higher time resolution allows us to monitor about 280 pulsars, including ten millisecond-pulsars (MSP). The format of the DFB data is "Psrfit". The "psrchive" program could reads and analyzes the data.The data could only be used with the permission of Dr. Na Wang (na.wang@xao.ac.cn), please send her an email for your request.The pulsar timing data were obtained with the Nanshan 25M radio telescope.

spm4.mainTable Info The SPM4 Catalog contains absolute proper motions, celestial coordinates, and B,V photometry for 103,319,647 stars and galaxies between the south celestial pole and -20 degrees declination. The catalog is roughly complete to V=17.5. It is based on photographic and CCD observations taken with the Yale Southern Observatory's double-astrograph at Cesco Observatory in El Leoncito, Argentina.

ucd.dataTable Info The Unified Content Descriptor (UCD) is a formal vocabulary astronomical data that is controlled by the International Virtual Observatory Alliance (IVOA). The vocabulary is restricted in order to avoid proliferation of terms and synonyms, and controlled in order to avoid ambiguities as far as possible. It is intended to be flexible, so that it is understandable to both humans and computers. UCDs describe astronomical quantities, and they are built by combining words from the controlled vocabulary.
