Plots of spectrogram slope versus
central frequency from least-squares fit,
for convergent events.
"Convergent" means first 5 fits converged (except maybe the first fit), OR
the cheating fit improved the chi-squared by a certain margin; i.e.,
itest = exits ge 30. 785 of 838 events were convergent.
| 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.
This sample consists of convergent events. |

| f0 vs alpha, medium
scale. |

| f0 vs alpha, small
