WebWe have simulated, using a Monte Carlo method, time series representing the aperiodic variability typically observed in some X-ray sources. We have supposed that such red-noise features are generated by a shot noise process. The resulting time series have been analyzed by fast Fourier transform techniques. Using different sets of parameters we …

Panel (a): the time series z(t) (left y-axis) and the standard deviation of the white noise component (right y-axis). Panel (b): the PS indicator in a sliding window of size of the length of the time series. Web30 de dez. de 2004 · Download PDF Abstract: We demonstrate a simple method for testing the significance of peaks in the periodogram of red noise data. The procedure was designed to test for spurious periodicities in X-ray light curves of active galaxies, but can be used quite generally to test for periodic components against a background noise …
