The upper series represents the slope of the spectrum In log- log space and varies randomly around the theoretical value of -1 as predicted by theory. Near 0° and 180°, the esti- mates become unstable due to poor sampling. The lower ser- ies represents the intercept of the spectrum in log-log space (or the coefficient of frequency) and agrees well with the sinusoid model predicted by theory. Notice the maximum intercept, and therefore total spectral energy, corresponds to a sample taken perpendicular to strike (azimuth = 90°). 85.
