Accessing Online Astronomical Data

Astroquery is an astropy affiliated package that contains a collection of tools to access online Astronomical data. Each web service has its own sub-package. For example, to interface with the SIMBAD website, use the simbad sub-package:

>>> from astroquery.simbad import Simbad
>>> theta1c = Simbad.query_object('tet01 Ori C')
>>> theta1c.pprint()
   MAIN_ID          RA           DEC      ... COO_QUAL COO_WAVELENGTH     COO_BIBCODE
------------- ------------- ------------- ... -------- -------------- -------------------
* tet01 Ori C 05 35 16.4637 -05 23 22.848 ...        A              O 2007A&A...474..653V

Installation and Requirements

Astroquery works with Python 2.7 and 3.3 or later. As an astropy affiliate, astroquery requires astropy version 0.4 or later.

astroquery uses the requests module to communicate with the internet. BeautifulSoup is needed for HTML parsing for some services. The keyring module is also required for accessing services that require a login. These can all be installed using pip.

The latest release of astroquery can be downloaded or pip installed:

$ pip install astroquery

Or directly from github:

$ pip install https://github.com/astropy/astroquery/archive/v0.2.tar.gz

If you’d like the latest development version, you can install it with the following commands:

$ git clone git@github.com:astropy/astroquery.git
$ cd astroquery
$ python setup.py install

pip install also works:

$ pip install git+http://github.com/astropy/astroquery.git#egg=astroquery

Using astroquery

Importing astroquery on its own doesn’t get you much: you need to import each sub-module specifically. Check out the docs to find a list of the tools available. The API shows the standard suite of tools common to most modules, e.g. query_object and query_region.

To report bugs and request features, please use the issue tracker. Code contributions are very welcome, though we encourage you to follow the API and contributing guidelines as much as possible.
