SIMBAD Astronomical Database - CDS (Strasbourg)
What is SIMBAD, and what is it not ? %WHAT IS SIMBAD
The purpose of Simbad is to provide information on astronomical objects of interest which have been studied in scientific articles.
Simbad is a dynamic database, updated every working day.
It provides the bibliography, as well as available basic information such as the nature of the object, its coordinates, magnitudes, proper motions and parallax, velocity/redshift, size, spectral or morphological type, and the multitude of names (identifiers) given in the literature. The CDS team also performs cross-identifications based on the compatibility of several parameters, in the limit of a reasonably good astrometry.
Simbad is a meta-compilation built from what is published in the literature, and from our expertise on cross-identifications. By construction it is highly inhomogeneous as data come from any kind of instruments at all wavelenghts with any resolution and astrometry, and different names from one publication to another.
Simbad is not a catalogue, and should not be used as a catalogue. The CDS also provides the VizieR database which contains published lists of objects, as well as most very large surveys. The idea now is to use both Simbad and VizieR as completary research tools.

Release history
Content
The SIMBAD astronomical database provides basic data, cross-identifications, bibliography and measurements for astronomical objects outside the solar system.
SIMBAD can be queried by object name, coordinates and various criteria. Lists of objects and scripts can be submitted.
Links to some other on-line services are also provided.
Basic search
identifier, coordinates (radius=10 arcmin), or bibcode

Statistics
Simbad contains on 2019.09.12
10,787,007 objects
35,350,514 identifiers
362,467 bibliographic references
19,898,929 citations of objects in papers
SIMBAD on the Web is the WWW interface to the SIMBAD database. It offers the following functionalities:
Query by identifiers and around identifiers
Query by coordinates, specifying the radius and the equinox
Query by bibcode and partial bibcode
Sampling with a set of physical criteria
Query by lists of objects, coordinates or bibcodes
Display charts for list of objects resulting from coordinates query
Moreover, the interface provides links with many other data services :
Links to the other CDS services: Tables in VizieR, giving access to the whole catalogued data, links to Aladin images, surveys and observatory logs.
Through the coordinates in basic data, you can query around an object, using a provided radius.
Identifiers are linked to the nomenclature dictionary, providing full description of original list, and, when available, offering direct access to the corresponding catalogue in the CDS catalogue service (VizieR and Bazaar)
Every bibcode is a link to the underlying bibliographic information, either at CDS, at ADS, or at the journal site when available. Links to the full text of paper are available in most cases.
For articles containing tables stored at CDS, the reference provides also a link to the table or catalogue.
A link to the Heasarc database (NASA/GSFC) is proposed when an object has identifiers in high energy catalogues.
IUE measurements contain an anchor which points to the spectra stored in the INES database.
The maps produced by coordinate queries are cliquable and return the object information from SIMBAD.
