# AsyncConeSearch

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

  Bases: `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)
