COMPARISONS OF POWER SPECTRUMS OF ARTIFICIAL TIME SERIES WITH SPECTRUM OF A SOLAR PLAGE INDEX.
Abstract
A number of experiments are described whose purpose was to determine whether peaks in power spectrums of time series of solar indices reflect a tendency for equidistant separation in longitude of solar active regions or are produced by the analysis technique. From comparisons of power spectrums of artificial time series with the spectrum of a solar plage index it is clear that there is no appreciable tendency for equidistant spacing of active regions.
