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:
astroquery.simbad (import Simbad>> > theta1c=Simbad.query_object ' tet 16 Ori C ' )>> > theta1c .pprint () MAIN_ID (RA) (DEC)version 2.0 or later.... (COO_QUAL
- ------------ - (...) -------- -------------- ------------------ - (tet) (Ori C) (0) (5)COO_WAVELENGTH
(COO_BIBCODE) ------------31.
astropy affiliate, astroquery requires (astropy( (0) (5) (5) 4493 (...) (AO) (A) (A) & (A) ... 656 , (V)
astroquery uses the requests module to communicate with the internet. BeautifulSoup and html5lib ‘ are needed for HTML parsing for some services. The the keyring module is also required for accessing services that require a login. These can all be installed using pip or anaconda . Running the tests requires curl to be installed.
The latest version of astroquery can be conda installed:
or pip installed:
and the ‘bleeding edge’ master version:
or cloned and installed from source:
# 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 $ cdastroquery $ python setup.py install Using astroqueryImporting 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
as much as possible.List of Modules
The following modules have been completed using a common API:
(Atomic Line List : A collection of more than , atomic transitions.
