compute_lightcurve_fvar

gammapy.estimators.utils.compute_lightcurve_fvar(lightcurve, flux_quantity='flux')

Compute the fractional excess variance of the input lightcurve.

Internally calls the compute_fvar function.

Parameters

lightcurveFluxPoints

The lightcurve object.

flux_quantitystr

Flux quantity to use for calculation. Should be ‘dnde’, ‘flux’, ‘e2dnde’ or ‘eflux’. Default is ‘flux’.

Returns

fvarTable

Table of fractional excess variance and associated error for each energy bin of the lightcurve.
