Using the vertical axis results, the data for each delivery location was used to determine the cumulative distribution function (CDF) of the RMS (G) and fitted in a modified Weibull distribution model [7]. The PSD levels shown in Figures 4-6 represent 100% of the CDF. The RMS (G) values were then evaluated to observe the distribution for each delivery location. Histograms containing the frequency and cumulative percentage of the RMS (G) values are presented in Figures 8-10.
