Methods Documentation

query_region(*args, **kwargs)

Queries the service and returns a table object.

Queries a region around the specified coordinates. Either a radius or both a height and a width must be provided.

Parameters:

coordinates : str or astropy.coordinates.

coordinates around which to query

radius : str or astropy.units.Quantity.

the radius of the cone search

width : str or astropy.units.Quantity

the width for a box region

height : str or astropy.units.Quantity

the height for a box region

get_query_payload : bool, optional

Just return the dict of HTTP request parameters.

cache: bool, optional

Use the astroquery internal query result cache

Returns:

table : A Table object.

Queries a region around the specified coordinates. Either a radius or both a height and a width must be provided.

Parameters:

coordinates : str or astropy.coordinates.

coordinates around which to query

radius : str or astropy.units.Quantity.

the radius of the cone search

width : str or astropy.units.Quantity

the width for a box region

height : str or astropy.units.Quantity
