apply_format(table)[source]
get_model(use_association_name=True, exposure=None, npred_min=0)[source]

Build the model with FGL sources.

Parameters:

  • use_association_name – use the name of the associated source (stored in assoc_name column)

  • exposure – exposure in cm2 * seconds (can be calculated with gtexposure)

  • npred_min – minimum number of predicted events.

Returns:
