gaia.dr3liteTable Info This is gaia_source from the Gaia Data Release 3, stripped to just enough columns to enable basic science (but therefore a bit faster and simpler to deal with than the full gaia_source table). Note that on this server, there is also The gedr3dist.main, which gives distances computed by Bailer-Jones et al. Use these in preference to working with the raw parallaxes. The full DR3 is available from numerous places in the VO (in particular from the TAP services ivo://uni-heidelberg.de/gaia/tap and ivo://esavo/gaia/tap). This schema contains data re-published from the official Gaia mirrors (such as ivo://uni-heidelberg.de/gaia/tap) either to support combining its data with local tables (the various Xlite tables) or to make the data more accessible to VO clients (e.g., epoch fluxes).
gaia.edr3liteTable Info This is a “light” version of the full Gaia DR3 gaia_source table. It is just a view copying gaia.dr3lite, which should preferentially be used in new queries. This table is being kept around in order to keep legacy queries from breaking unnecessarily. However, it is actually DR3 data rather than eDR3. The minute differences did not seem to warrant keeping two copies of the relatively massive data around. This schema contains data re-published from the official Gaia mirrors (such as ivo://uni-heidelberg.de/gaia/tap) either to support combining its data with local tables (the various Xlite tables) or to make the data more accessible to VO clients (e.g., epoch fluxes).

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). Note that this shouldn't really be necessary as all information present here should be exposed through Registry records. However, in reality data providers currently are much more liable to give column metadata in their tap_schema than in their Registry records. Hence, for the time being, we maintain this service by harvesting tap_schemas about monthly.
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.

liujun.liujunTable InfoN/AActive Galactic Nuclei (AGNs) are extragalactic objects characterized by extremely complex physical processes and strong temporal flux variability over almost the whole electromagnetic spectrum, which play a very important role in studying the formation and evolution of galaxies, cosmology and many other astrophysical problems. Flux variability is one of the most remarkable observational characteristics of AGNs and the variability time scales are from minutes to dozens of years. Multi-wavelength flux monitoring is the main means to study the nature of AGN flux variability. In order to systematically study the total flux variability of AGNs in radio band, we launched a long-term program, which is called the quasi- Simultaneous Multiwavelength Monitoring of AGNs with the Nanshan 26-m radio telescope of Xinjiang Astronomical Observatory (XAO), namely SMMAN program. The monitoring data were acquired monthly with the cross-scan mode at C-band (4.8 GHz) and K-band (23.6 GHz) for a sample of about 100 AGNs selected from Fermi-LAT suvery. Additionally, we also conducted weekly monitoring observations or Intra-Day Vairibility (IDV) observations for some of flaring Blazars to reveal their more complex variability time scales.

obscode.dataTable InfoN/A 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.
ppmxl.mainTable InfoN/A 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 InfoN/AThe 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. 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. Timing observations of 74 pulsars have been regularly carried out between 2002 July to 2009 December. These 74 pulsars have been monitored approximately once every 9d using a dual-channel cryogenic system that receives orthogonal linear polarizations at the central observing frequency of 1540 MHz. The folded profiles obtained are released in format PSRFITS for timing analysis, the file name extension is .FTp. Users can enter "~*.FTp*" in "Product key" filed to search and download it. Non-public data could be used with the permission of Dr. Na Wang (na.wang@xao.ac.cn), please send an email for your request.
pulsarcatalog.dataTable InfoN/A The Australia Telescope National Facility (ATNF) Pulsar Catalog is a catalog of known pulsars compiled by R.N. Manchester et al. and is descended from pulsar database used for the paper "Catalog of 558 Pulsars" by J.H. Taylor, R.N. Manchester and A.G. Lyne 1993, ApJS, 88, 529-568. The current catalog has been supplemented by inclusion of published data from more recent radio surveys, in particular, the Parkes Multibeam (PM) Pulsar Survey (Manchester et al. 2001, MNRAS, 328, 17-35) [available at the HEASARC as the PMPULSAR table] and the Swinburne Intermediate Latitude Pulsar Survey (Edwards et al. 2001, MNRAS, 326, 358-374), both made using the ATNF Parkes 64-m radio telescope. Binary parameters for known binary pulsars are also included as well as all available astrometric and spin parameter information for all pulsars. The catalog includes all published rotation-powered pulsars. Two separate small subsets of pulsars detected ONLY at high energies are also included in the current table: the first group comprises X-ray and gamma-ray pulsars which are apparently powered by spin-down energy, but which have not been detected at radio wavelengths, while the second group contains anomalous X-ray pulsars (AXPs) and soft-gamma-ray repeaters (SGRs) for which coherent pulsations have been detected. Accretion-powered pulsars such as Her X-1 and the recently discovered X-Ray millisecond pulsars such as SAX J1808.4-3658 are not included in this table, however. Many people have contributed to the compilation of the data contained in this catalog and the database that it was derived from. The authors particularly thank Andrew Lyne of the University of Manchester, Jodrell Bank Observatory, David Nice of Princeton University, and Russell Edwards, then at Swinburne University of Technology. The also acknowledge the efforts of Warwick University students Adam Goode and Steven Thomas who compiled and checked a recent version of the database. The original (summer 2003) database at the ATNF website was compiled with the invaluable assistance of Maryam Hobbs, while the ATNF web interface was designed and constructed by Albert Teoh, a Summer Vacation Scholar at the ATNF in 2002/2003. The authors would appreciate if anyone making use of this catalog in a publication acknowledges the source of their information by quoting the ATNF Pulsar Catalog website address of http://www.atnf.csiro.au/research/pulsar/psrcat/
spm4.mainTable InfoN/A 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 InfoN/A 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.
wugang.wugangTable InfoN/A The molecular spectrum lines data include mainly ammonia and water masers lines at 1.3cm band, as well as formaldehyde and recombination lines at 6cm band observed towards both our Galactic plane and nearby molecular clouds and star-forming regions.
