Affiliated Package: Astroquery¶

Astroquery is an Astropy-affiliated package that contains a collection of tools to access online Astronomical data. To install it, do:

pip install astroquery

The following modules have been completed using a common API:

SIMBAD Queries (astroquery.simbad)
VizieR Queries (astroquery.vizier)
IRSA Dust Extinction Service Queries (astroquery.irsa_dust)
NED Queries (astroquery.ned)
Splatalogue Queries (astroquery.splatalogue)
IRSA Queries (astroquery.irsa)
UKIDSS Queries (astroquery.ukidss)
MAGPIS Queries (astroquery.magpis)
NRAO Queries (astroquery.nrao)
Besancon Queries (astroquery.besancon)
NIST Queries (astroquery.nist)
NVAS Queries (astroquery.nvas)
GAMA Queries (astroquery.gama)
ESO Queries (astroquery.eso)
xMatch Queries (astroquery.xmatch)
Atomic Line List (astroquery.atomic)
ALMA Queries (astroquery.alma)
Skyview Queries (astroquery.skyview)
NASA ADS Queries (astroquery.nasa_ads)
HEASARC Queries (astroquery.heasarc)

These others are functional, but do not follow a common & consistent API:

Fermi Queries (astroquery.fermi)
SDSS Queries (astroquery.sdss)
ALFALFA Queries (astroquery.alfalfa)
Spitzer Heritage Archive (astroquery.sha)
LAMDA Queries (astroquery.lamda)
OGLE Queries (astroquery.ogle)
Open Exoplanet Catalogue(astroquery.open_exoplanet_catalogue)
CosmoSim Queries (astroquery.cosmosim)

SIMBAD¶

As an example, let's run a SIMBAD query:

from astropy import units as u
from astroquery.simbad import Simbad

r = Simbad.query_region('m42', radius=3. * u.arcmin)

r.colnames

['MAIN_ID',
 'RA',
 'DEC',
 'RA_PREC',
 'DEC_PREC',
 'COO_ERR_MAJA',
 'COO_ERR_MINA',
 'COO_ERR_ANGLE',
 'COO_QUAL',
 'COO_WAVELENGTH',
 'COO_BIBCODE']

r

WISE¶

from astroquery.irsa import Irsa

Irsa.query_region('m42', catalog='wise_allsky_4band_p3as_psd', radius=10*u.arcmin)

Practical Exercise¶

Go to the documentation and try out a query interface for a service that might be relevant to you!
