center : tuple of float or Astronomical Coordinate Systems (astropy.coordinates)
Right-ascension and declination for the position of
the center of the cone to search:
- If tuple of float is given, it is assumed to be
(RA, DEC) in the ICRS coordinate system,
given in decimal degrees.
- If astropy coordinates object is given, it will
be converted internally to
ICRS.
radius : float or Angle object
Radius of the cone to search:
- If float is given, it is assumed to be in decimal degrees.
- If astropy angle object or angular quantity is given,
it is internally converted to degrees.
verb : {1, 2, 3}
Verbosity indicating how many columns are to be returned
in the resulting table. Support for this parameter by
a Cone Search service implementation is optional. If the
service supports the parameter:
- Return the bare minimum number of columns that
the provider considers useful in describing the
returned objects.
- Return a medium number of columns between the
minimum and maximum (inclusive) that are
considered by the provider to most typically
useful to the user.
- Return all of the columns that are available for
describing the objects.
If not supported, the service should ignore the parameter
and always return the same columns for every request.
catalog_db :
May be one of the following, in order from easiest to
use to most control:
- None: A database of
astropy.vo.client.conesearch.CONESEARCH_DBNAME
catalogs is downloaded from
astropy.vo.client.vos_catalog.BASEURL. The first
catalog in the database to successfully return a result is used.
- catalog name: A name in the database of
astropy.vo.client.conesearch.CONESEARCH_DBNAME
catalogs at astropy.vo.client.vos_catalog.BASEURL is used.
For a list of acceptable names, use list_catalogs().
- url: The prefix of a URL to a IVOA Service for
astropy.vo.client.conesearch.CONESEARCH_DBNAME.
Must end in either ‘?’ or ‘&’.
- VOSCatalog object: A specific catalog manually downloaded and
selected from the database (see General VO Services Access).
- Any of the above 3 options combined in a list, in which case
they are tried in order.
pedantic : bool or None
When True, raise an error when the file violates the spec,
otherwise issue a warning. Warnings may be controlled using
warnings module.
When not provided, uses the configuration setting
astropy.io.votable.table.PEDANTIC, which defaults to False.
verbose : bool
cache : bool
Use caching for VO Service database. Access to actual VO
websites referenced by the database still needs internet
connection.
