I am trying to get the frequency information from a q-transform plot shown below.
I am using the following code snippet to get that information, but I see that the following code prints the frequency values for the complete q-transform plot.
hq = strain.q_transform(outseg=(t0-dt, t0+dt))
freq = hq.frequencies
What I want is only the frequency values that are associated with the classic hockey stick pattern(places where normalized energy is greater than ~80) waveform in the q-transform plot.
Thanks for the help.
