4. Flucstrucs¶
This reflects the latest version which optionally splits the spectrum up into bands based on the strongest peaks.
4.1. 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.
