plot_periodogram¶

gammapy.time.plot_periodogram(time, flux, periods, power, flux_err=None, best_period=None, fap=None)[source]¶

Plot a light curve and its periodogram.

The highest period of the periodogram and its false alarm probability (FAP) is added to the plot, if given.

Parameters

timenumpy.ndarray: Time array of the light curve
fluxnumpy.ndarray: Flux array of the light curve
periodsnumpy.ndarray: Periods for the periodogram
powernumpy.ndarray: Periodogram peaks of the data
flux_errnumpy.ndarray (optional, default=None): Flux error array of the light curve. Is set to 0 if not given.
best_periodfloat (optional, default=None): Period of the highest periodogram peak
fapfloat (optional, default=None): False alarm probability of best_period under a certain significance criterion.

Returns
