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:

time : numpy.ndarray: Time array of the light curve
flux : numpy.ndarray: Flux array of the light curve
periods : numpy.ndarray: Periods for the periodogram
power : numpy.ndarray: Periodogram peaks of the data
flux_err : numpy.ndarray (optional, default=None): Flux error array of the light curve. Is set to 0 if not given.
best_period : float (optional, default=None): Period of the highest periodogram peak
fap : float (optional, default=None): False alarm probability of best_period under a certain significance criterion.

Returns:
