********************************** Fermi Queries (`astroquery.fermi`) ********************************** Getting started =============== The following example illustrates a Fermi LAT query, centered on M 31 for the energy range 1 to 100 GeV for the first day in 2013. .. doctest-remote-data:: >>> from astroquery.fermi import FermiLAT >>> result = FermiLAT.query_object('M31', energyrange_MeV='1000, 100000', ... obsdates='2013-01-01 00:00:00, 2013-01-02 00:00:00') >>> print(result) # doctest: +IGNORE_OUTPUT ['https://fermi.gsfc.nasa.gov/FTP/fermi/data/lat/queries/L210111120827756AAA3A88_PH00.fits', 'https://fermi.gsfc.nasa.gov/FTP/fermi/data/lat/queries/L210111120827756AAA3A88_SC00.fits'] Troubleshooting =============== If you are repeatedly getting failed queries, or bad/out-of-date results, try clearing your cache: .. code-block:: python >>> from astroquery.fermi import FermiLAT >>> FermiLAT.clear_cache() If this function is unavailable, upgrade your version of astroquery. The ``clear_cache`` function was introduced in version 0.4.7.dev8479. Reference/API ============= .. automodapi:: astroquery.fermi :no-inheritance-diagram:
