PhaseBackgroundEstimator

class gammapy.background.PhaseBackgroundEstimator(on_region, on_phase, off_phase, observations)

Bases: object

Background estimation with on and off phases.

This class is responsible for creating a BackgroundEstimate by counting events in the on-phase-zone and off-phase-zone in an ON-region, given an observation, an on_region, an on-phase-zone, an off-phase-zone.

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_region : CircleSkyRegion

Target region in the sky

observations : Observations

Observations to process

on_phase : tuple or list of tuples

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

off_phase : tuple or list of tuples

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

Methods Summary

filter_events(events, tuple_phase_zone)	Select events depending on their phases.
process(self, obs)	Estimate background for one observation.
run(self)	Run all steps.
