Figure 9. (upper curve) Averaged spectral ratios for the caustic events (17–22)
measured at station 11 divided by average spectra over stations 1–6. The
smooth curve is a fit of the caustic
equation (10) to the data. The
lower curve is the averaged spectral ratios for the noncaustic events. It has
both lower amplitude and a flat variation that is consistent with the assumption
that stations 1–6 are representative of noncaustic behavior.
