Flucstrucs ========== This reflects the latest version which optionally splits the spectrum up into bands based on the strongest peaks. Definitions ----------- Shot: shot time: The time of the mid point of the fluctuation found SVS: The sigular values present in the FS, in the order of the SVS freq: the dominant frequency of the fs Amp: estimated amplitude (normalisation distorts this) a12: the ratio a2/a1, the th relative strength of the second largest SV in the FS p : H: Entropy of the FS frlow, frhigh: The range of the bandpass filter used to extract this if any. If no filter is used, frhigh= nyquist. If 1 band is used, frhigh=0.98*nyquist so that the filter mask avoids aliasing. cpkf: channel peaking factor - how much the peak channel exceeds the others fpkf: frequency peaking factor - sim but freq phases - actually nearest neighbour phases differences.
