threeML.catalogs.Fermi module
- class threeML.catalogs.Fermi.FermiGBMBurstCatalog(update=False)[source]
Bases:
VirtualObservatoryCatalog
- get_detector_information()[source]
Return the detectors used for spectral analysis as well as their background intervals. Peak flux and fluence intervals are also returned as well as best fit models
- Returns
detector information dictionary
- get_model(model='band', interval='fluence')[source]
Return the fitted model from the Fermi-LAT GBM catalog in 3ML Model form. You can choose band, comp, plaw, or sbpl models corresponding to the models fitted in the GBM catalog. The interval for the fit can be the ‘fluence’ or ‘peak’ interval
- Parameters
model – one of ‘band’ (default), ‘comp’, ‘plaw’, ‘sbpl’
interval – ‘peak’ or ‘fluence’ (default)
- Returns
a dictionary of 3ML likelihood models that can be fitted

- fix_point_sources_within_radius(radius, normalization_only=True)[source]
Fixes the parameters for the point sources within the given radius of the center of the search cone
- Parameters
radius – radius in degree
normalization_only – if True, fixes only the normalization of the source (default: True)
- Returns
none
- free_point_sources_within_radius(radius, normalization_only=True)[source]
Free the parameters for the point sources within the given radius of the center of the search cone
- Parameters
radius – radius in degree
normalization_only – if True, frees only the normalization of the source (default: True)
- Returns
none
