On the power spectrum of “red noise.”
Web27 de abr. de 2016 · The standard method of estimating power spectral density (PSD) of AGN variability is easily affected by systematic biases such as red-noise leakage and aliasing, in particular, when the observation spans a relatively short period and is gapped. WebWe discuss techniques of modelling the power spectrum of variability in cases where the spectral power is continuous but diverges strongly to low frequencies (so-called `red …
