The generalised lomb-scargle periodogram

Web7 Aug 2000 · This generalized Lomb-Scargle periodogram is the sufficient statistic for single frequency estimation in a wide class of problems ranging from stationary frequency estimation in real... WebCalculate the Lomb-Scargle periodogram. The constructor of LombScargle takes a TimeSeries instance, i.e., a light curve object, as first argument. It then computes the usual Lomb-Scargle periodogram using a fast algorithm. The frequency array is constructed on the fly based on the oversampling keywords, which are mandatory in this case.
