Methods Documentation

get_columns(mission=None, dataset=None, table=None)[source]

Get the schema for a given table.

Parameters
missionstr

The mission to be used (if not the default mission).

datasetstr

The dataset to be used (if not the default dataset).

tablestr

The table to be queried (if not the default table).

Returns
tableTable

A table containing a description of the columns

list_datasets(mission=None, cache=True)[source]

For a given mission, list the available datasets

Parameters
missionstr

A mission name. Must be one of the valid missions from list_missions. Defaults to the configured Mission

cachebool

Cache the query result

Returns
datasetslist

A list of dataset names

list_missions(cache=True)[source]

Return a list of the available missions

Parameters
cachebool

Cache the query result

list_tables(mission=None, dataset=None, cache=True)[source]

For a given mission and dataset (see list_missions, list_datasets), return the list of valid table names to query.

Parameters
missionstr

A mission name. Must be one of the valid missions from list_missions. Defaults to the configured Mission

datasetstr

A dataset name. Must be one of the valid dataset from list_datsets(mission). Defaults to the configured Dataset

cachebool

Cache the query result

Returns
tableslist

A list of table names

query_region(coordinate=None, where=None, mission=None, dataset=None, table=None, columns=None, width=None, height=None, intersect='OVERLAPS', most_centered=False)[source]

For certain missions, this function can be used to search for image and catalog files based on a point, a box (bounded by great circles) and/or an SQL-like where clause.

If coordinates is specified, then the optional width and height arguments control the width and height of the search box. If neither width nor height are provided, then the search area is a point. If only one of width or height are specified, then the search area is a square with that side length centered at the coordinate.

Parameters
coordinatestr, astropy.coordinates object

Gives the position of the center of the box if performing a box search. If it is a string, then it must be a valid argument to SkyCoord. Required if where is absent.

wherestr

SQL-like query string. Required if coordinates is absent.

missionstr

The mission to be used (if not the default mission).

datasetstr

The dataset to be used (if not the default dataset).

tablestr

The table to be queried (if not the default table).

columnsstr, list

A space-separated string or a list of strings of the names of the columns to return.

widthstr or Quantity object

Width of the search box if coordinates is present.

The string must be parsable by Angle. The appropriate Quantity object from astropy.units may also be used.

heightstr, Quantity object

Height of the search box if coordinates is present.

The string must be parsable by Angle. The appropriate Quantity object from astropy.units may also be used.

intersect'COVERS', 'ENCLOSED', 'CENTER', 'OVERLAPS'

Spatial relationship between search box and image footprint.

'COVERS': X must completely contain S. Equivalent to 'CENTER' and 'OVERLAPS' if S is a point.

'ENCLOSED': S must completely contain X. If S is a point, the query will always return an empty image table.

'CENTER': X must contain the center of S. If S is a point, this is equivalent to 'COVERS' and 'OVERLAPS'.

'OVERLAPS': The intersection of S and X is non-empty. If S is a point, this is equivalent to 'CENTER' and 'COVERS'.

most_centeredbool

If True, then only the most centered image is returned.

Returns
tableTable

A table containing the results of the query

query_region_async(coordinate=None, where=None, mission=None, dataset=None, table=None, columns=None, width=None, height=None, action='search', intersect='OVERLAPS', most_centered=False)[source]

For certain missions, this function can be used to search for image and catalog files based on a point, a box (bounded by great circles) and/or an SQL-like where clause.

If coordinates is specified, then the optional width and height arguments control the width and height of the search box. If neither width nor height are provided, then the search area is a point. If only one of width or height are specified, then the search area is a square with that side length centered at the coordinate.

Parameters
coordinatestr, astropy.coordinates object

Gives the position of the center of the box if performing a box search. If it is a string, then it must be a valid argument to SkyCoord. Required if where is absent.

wherestr

SQL-like query string. Required if coordinates is absent.

missionstr

The mission to be used (if not the default mission).

datasetstr

The dataset to be used (if not the default dataset).

tablestr

The table to be queried (if not the default table).

columnsstr, list

A space-separated string or a list of strings of the names of the columns to return.

widthstr or Quantity object

Width of the search box if coordinates is present.

The string must be parsable by Angle. The appropriate Quantity object from astropy.units may also be used.

heightstr, Quantity object

Height of the search box if coordinates is present.

The string must be parsable by Angle. The appropriate Quantity object from astropy.units may also be used.

intersect'COVERS', 'ENCLOSED', 'CENTER', 'OVERLAPS'

Spatial relationship between search box and image footprint.

'COVERS': X must completely contain S. Equivalent to 'CENTER' and 'OVERLAPS' if S is a point.

'ENCLOSED': S must completely contain X. If S is a point, the query will always return an empty image table.

'CENTER': X must contain the center of S. If S is a point, this is equivalent to 'COVERS' and 'OVERLAPS'.

'OVERLAPS': The intersection of S and X is non-empty. If S is a point, this is equivalent to 'CENTER' and 'COVERS'.

most_centeredbool

If True, then only the most centered image is returned.

action'search', 'data', or 'sia'

The action to perform at the server. The default is 'search', which returns a table of the available data. 'data' requires advanced path construction that is not yet supported. 'sia' provides access to the ‘simple image access’ IVOA protocol

Returns
responseResponse

The HTTP response returned from the service

query_region_sia(coordinate=None, mission=None, dataset=None, table=None, width=None, height=None, intersect='OVERLAPS', most_centered=False)[source]

Query using simple image access protocol. See query_region for details. The returned table will include a list of URLs.

show_docs(mission=None, dataset=None, table=None)[source]

Open the documentation for a given table in a web browser.

Parameters
missionstr

The mission to be used (if not the default mission).

datasetstr

The dataset to be used (if not the default dataset).

tablestr

The table to be queried (if not the default table).
