Elimination of long‐term variations from chaotic light curves
2013
We performed a comparative dynamical investigation of chaotic test data using the global flow reconstruction method. We demonstrate that large-amplitude, long-term variations may have a disturbing effect for the analysis. The Empirical Mode Decomposition method (EMD) and the Fourier filtering were tested to remove the additional variations. Test results show that the elimination of these variations significantly increased the robustness of the reconstructions. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
