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..653VInstallation and Requirements
As an astropy affiliate, astroquery requires astropy. However, because astroquery relies heavily upon the astropy.coordinates module, the development version of astropy is required. astropy can be installed from pip:
$ pip install git+http://github.com/astropy/astropy.git#egg=astropyastroquery uses the requests module to communicate with the internet. requests can also be installed with pip.
As of July 2013, astroquery is in pre-release state, so to install, you need to clone it:
$ git clone git@github.com:astropy/astroquery.git
$ cd astroquery
$ python setup.py installpip install also works:
$ pip install git+http://github.com/astropy/astroquery.git#egg=astroqueryUsing 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.
