Web23 Jul 2024 · In Zechmeister & Kürster (2009) the harmonic model of the LS periodogram is directly extended with the addition of a constant term, which has become known as the generalised Lomb-Scargle (GLS) periodogram. Moreover, both of these studies give the formulations allowing nonconstant noise variance.
