AsyncConeSearch

class astroquery.vo_conesearch.conesearch.AsyncConeSearch(*args, **kwargs)

Bases: astroquery.vo_conesearch.vo_async.AsyncBase

Perform a Cone Search asynchronously and returns the result of the first successful query.

Note

See AsyncBase for more details.

Parameters

args, kwargs

See conesearch().

Examples

>>> from astropy import coordinates as coord
>>> from astropy import units as u
>>> from astroquery.vo_conesearch import conesearch
>>> c = coord.ICRS(6.0223 * u.degree, -72.0814 * u.degree)
>>> async_search = conesearch.AsyncConeSearch(
...     c, 0.5 * u.degree,
...     catalog_db='Guide Star Catalog 2.3 Cone Search 1')

Check search status:

>>> async_search.running()
True
>>> async_search.done()
False

Get search results after a 30-second wait (not to be confused with astroquery.vo_conesearch.conf.timeout that governs individual Cone Search queries). If search is still not done after 30 seconds, TimeoutError is raised. Otherwise, Cone Search result is returned and can be manipulated as in Simple Cone Search Examples. If no timeout keyword given, it waits until completion:

>>> async_result = async_search.get(timeout=30)
>>> len(async_result)
