Title:: ADQL Query
Short Name:: gavoadql
Date:: 25 Jun 2024 10:32:04
Publisher:: Xinjiang Astronomical Observatory,CAS
Description:: An endpoint for submitting ADQL queries to the data center and retrieving the result in various forms.

Title:: FAST Pulsar Data Query Test
Short Name:: Pulsar_web
Date:: 25 Jun 2024 10:32:03
Publisher:: Xinjiang Astronomical Observatory,CAS
Description:: 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.

ID:: ivo://xaovo/gaia/q3/cone
Title:: Gaia DR3 Lite Cone Search
Short Name:: DR3 lite Cone
Date:: 25 Jun 2024 10:32:03
Publisher:: Xinjiang Astronomical Observatory,CAS
Description:: 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).

ID:: ivo://xaovo/gaia/q3/dr3lite
Title:: Gaia DR3 source catalogue "light"
Short Name:: gaia.dr3lite
Date:: 25 Jun 2024 10:32:03
Publisher:: Xinjiang Astronomical Observatory,CAS
Description:: 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).

Title:: Global TAP Schema Simple Search
Short Name:: GloTS plain
Date:: 25 Jun 2024 10:32:03
Publisher:: Xinjiang Astronomical Observatory,CAS
Description:: 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.

Title:: PPMXL Catalog Cone Search
Short Name:: XAO PPMXL
Date:: 25 Jun 2024 10:32:03
Publisher:: Xinjiang Astronomical Observatory,CAS
Description:: 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.

Title:: XAO AGN Flux Monitoring Data
Short Name:: liujun_web
Date:: 25 Jun 2024 10:32:03
Publisher:: Xinjiang Astronomical Observatory,CAS
Description:: 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.

Title:: XAO DC Custom Uploading Crossmatcher
Short Name:: xao_crossmatch
Date:: 25 Jun 2024 10:32:03
Publisher:: Xinjiang Astronomical Observatory,CAS
Description:: A plain positional crossmatch service that allows file and URL uploads to be crossmatched to DC-internal tables. In general, you want to use TAP for this kind of thing when it is available, but in a pinch it might come in handy. Larger catalogues that can be matched against include GAIA,PPMXL,ATNF Pulsar Catalog, and more.
