Methods Documentation

query_aliases(object_name, *, cache=None)

Search for aliases for a given confirmed planet or planet host

Parameters

object_namestr

The name of a planet or star to regularize using the aliastable table.

cachebool, optional

Should the request result be cached? This can be useful for large repeated queries, but since the data in the archive is updated regularly, this defaults to False.

Returns

responselist

A list of aliases found for the object name. The default name will be listed first.

query_criteria(*args, **kwargs)

Queries the service and returns a table object.

Search a table given a set of criteria or return the full table

The syntax for these queries is described on the Exoplanet Archive API documentation page [1]. In particular, the most commonly used criteria will be select and where.

Parameters

tablestr

The name of the table to query. A list of the tables on the Exoplanet Archive can be found on the documentation page [1].

get_query_payloadbool, optional

Just return the dict of HTTP request parameters. Defaults to False.

cachebool, optional

Should the request result be cached? This can be useful for large repeated queries, but since the data in the archive is updated regularly, this defaults to False.

**criteria

The filtering criteria to apply. These are described in detail in the archive documentation [1], but some examples include select="*" to return all columns of the queried table or where=pl_name='K2-18 b' to filter a specific column.

Returns

tableA Table object.

Returns

responserequests.Response

The HTTP response returned from the service.

query_object(*args, **kwargs)

Queries the service and returns a table object.

Search the global tables for information about a confirmed planet or planet host

The tables available to this query are the following (more information can be found on the archive’s documentation page [1]):

• exoplanets: This table contains parameters derived from a single, published reference that are designated as the archive’s default parameter set.

• compositepars: This table contains a full set of parameters compiled from multiple, published references.

• exomultpars: This table includes all sets of planet and stellar parameters for confirmed planets and hosts in the archive.

Parameters

object_namestr

The name of the planet or star. If regularize is True, an attempt will be made to regularize this name using the aliastable table.

table["exoplanets", "compositepars", or "exomultpars"], optional

The table to query, must be one of the supported tables: "exoplanets", "compositepars", or "exomultpars". Defaults to "exoplanets".

get_query_payloadbool, optional

Just return the dict of HTTP request parameters. Defaults to False.

cachebool, optional

Should the request result be cached? This can be useful for large repeated queries, but since the data in the archive is updated regularly, this defaults to False.

regularizebool, optional

If True, the aliastable will be used to regularize the target name.

**criteria

Any other filtering criteria to apply. Values provided using the where keyword will be ignored.

Returns

tableA Table object.
