================================== Accessing Online Astronomical Data ==================================

Astroquery is an astropy <http://www.astropy.org>_ 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 <http://simbad.u-strasbg.fr/simbad/>_, use the simbad sub-package:

.. code-block:: python

>>> 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 3.7 or later. As an astropy_ affiliate, astroquery requires astropy_ version 4.0 or later.

astroquery uses the requests <http://docs.python-requests.org/en/latest/>_ module to communicate with the internet. BeautifulSoup <http://www.crummy.com/software/BeautifulSoup/>_ and html5lib' <https://html5lib.readthedocs.io/en/latest/>_ are needed for HTML parsing for some services. The keyring <https://pypi.python.org/pypi/keyring>_ module is also required for accessing services that require a login. These can all be installed using pip <https://pypi.python.org/pypi/pip>_ or anaconda <http://continuum.io/>. Running the tests requires curl <https://curl.haxx.se/> to be installed.

The latest version of astroquery can be conda installed:

.. code-block:: bash

$ conda install -c conda-forge astroquery

or pip installed:

.. code-block:: bash

$ pip install --pre astroquery

and the 'bleeding edge' main version:

.. code-block:: bash

$ pip install https://github.com/astropy/astroquery/archive/main.zip

or cloned and installed from source:

.. code-block:: bash

$ # If you have a github account:
$ git clone [email protected]:astropy/astroquery.git
$ # If you do not:
$ git clone https://github.com/astropy/astroquery.git
$ cd astroquery
$ python setup.py install

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 <https://github.com/astropy/astroquery/blob/main/CONTRIBUTING.rst>_ as much as possible.
