Incorrect versions of Figures
5 and 6 containing
normalization errors were accidentally published by
Borcherdt
(2002). They should be replaced with the figures shown here. The
text and tabulated regression values published in
Borcherdt (2002)
are correct and refer to the figures shown here.

Figure 5. Borcherdt—Average spectral ratio for the short-period band for site
class D (a) and site class C (b). The empirical data as derived using the
hypocentral distance norm and the Abrahamson and Silva (A&S) spectral norm at
0.3 sec are plotted on each figure. Corresponding regression curves, 95%
confidence limits for the observed values, and the 80% confidence limits for the
ordinate to the true population regression line are shown.

Figure 6. Borcherdt—Average spectral ratio for the mid-period band for site
classes D and C. The empirical data as derived using the hypocentral distance
norm and the Abrahamson and Silva (A&S) spectral norm at 1.0 sec are plotted on
each figure. Corresponding regression curves, 95% confidence limits for the
observed values, and the 80% confidence limits for the ordinate to the true
population regression line are shown.
