glots.columns | Table Info | A 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.services | Table Info | A table of TAP services harvested from the registry (and some

liujun.liujun | Table Info | N/A | Active 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.data | Table Info | N/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.main | Table Info | N/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.pulsar | Table Info | N/A | The 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

pulsarcatalog.data | Table Info | N/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

spm4.main | Table Info | N/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.data | Table Info | N/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. |
