The data
The data analyzed in our study is available on this page. The sampling rate of the data was 173.61 Hz. For a more detailed description of the data please refer to the manuscript Please note, however, that the time series have the spectral bandwith of the aquisition system, which is 0.5 Hz to 85 Hz. The application of a low-pass filter of 40 Hz, as described in the manuscript, is regarded as the first step of analysis and therefore not carried out for the downloadable time series. Everyone is invited to send their comments or questions by email: ralphandrzejak@ yahoo.de (remove the spaces in the address)
