Plots of spectrogram slope versus central frequency from least-squares fit, for JASA paper.

Slope of spectrogram alpha versus central frequency f0, large scale (all events on the plot). The numbers in the upper-right-hand corner of each plot are: total number of events, number of events on the plot, (and, for the 1-D plots) mean and standard deviation for the distribution.

IDL program rdfit.pro used to read in data from least-squares fits.
IDL program plotbw4 used to make the graphs above.
