SensitivityMakerBase

class ctapipe.irf.benchmarks.SensitivityMakerBase(**kwargs: Any)

Bases: DefaultRecoEnergyBins

Base class for calculating the point source sensitivity.

This uses pyirf.binning.create_bins_per_decade to create an energy binning with exactly reco_energy_n_bins_per_decade bins per decade, to comply with CTAO requirements. All other benchmarks/ IRF components prioritize respecting the lower and upper bounds for the energy binning over creating exactly n_bins_per_decade bins per decade.

Attributes Summary

alpha

Size ratio of on region / off region.

Methods Summary

__call__(signal_events, background_events, ...)

Calculate the point source sensitivity based on pyirf.sensitivity.calculate_sensitivity.

Methods Documentation

abstract __call__(signal_events: QTable, background_events: QTable, spatial_selection_table: QTable, gamma_spectrum: Spectra, extname: str = 'SENSITIVITY') → BinTableHDU

Calculate the point source sensitivity based on pyirf.sensitivity.calculate_sensitivity.

Parameters:

signal_events: astropy.table.QTable

Reconstructed signal events to be used.

background_events: astropy.table.QTable

Reconstructed background events to be used.

spatial_selection_table: QTable

Direction cut that was applied on signal_events.

gamma_spectrum: ctapipe.irf.Spectra

Spectra by which to scale the relative sensitivity to get the flux sensitivity.

extname: str

Name of the BinTableHDU.

Returns:

BinTableHDU
