PhaseBackgroundMaker

class gammapy.makers.PhaseBackgroundMaker(on_phase, off_phase)

Bases: object

Background estimation with on and off phases.

TODO: For a usage example see future notebook.

TODO: The phase interval has to be between 0 and 1. Cases like [-0.1, 0.1], for example, are still not supported.

Parameters

on_phasetuple or list of tuples

on-phase defined by the two edges of each interval (edges are excluded)

off_phasetuple or list of tuples

off-phase defined by the two edges of each interval (edges are excluded)

Methods Summary

make_counts(self, dataset, observation)	Make off counts.
make_counts_off(self, dataset, observation)	Make off counts.
run(self, dataset, observation)	Run all steps.
