Web13 Apr 2024 · In this paper, we propose the multitaper-Lomb–Scargle (MTLS) statistic: a method for time-series analysis that combines the multitaper approach with the LS technique. The method is a rapid computation of the multitaper spectral statistic (Thomson 1982) under irregular sampling.
WebThe multi-harmonic periodogram ( [Bretthorst1988], [SchwarzenbergCzerny1996]) is another extension of Lomb-Scargle that fits a truncated Fourier series to the data at each trial frequency. This algorithm can also be made to scale as HN_f logHN_f [Palmer2009]. However, the multi-harmonic periodogram is fundamentally different than template fitting. condor wet leaseWebExample of a Lomb-Scargle periodogram.
