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.
>>> 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)
['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If you are repeatedly getting failed queries, or bad/out-of-date results, try clearing your cache:
>>> 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.
