If a binned time series is passed, the time at the center of the bins is used. Also note that this method automatically gets rid of NaN/undefined values when initializing the periodogram. Parameters ---------- signal_column_name : str The name of the column containing the signal values to use. uncertainty : str or float or `~astropy.units.Quantity`, optional The name of the column containing the errors on the signal, or the value to use for the error, if a scalar. **kwargs Additional keyword arguments are passed to the initializer for this periodogram class.
