ave.info Gives
rough explanation of how the analysis results were averaged, and describes the
correspondence between the numbers in the names of files stored in this folder

response characteristics. The letter "n" stands for the north-south
component.
DIFINSTRES1_2u.d The file name is short for Difference in

* In the above data files,
the frequency, the mean of segment-by-segment analysis results and the standard
deviation are laid out in the first, second and third columns, respectively.
For data with a note "(logarithmic mean)" in parentheses, the
frequency, the mean, the mean minus a standard deviation and the mean plus a
standard deviation are laid out in the first, second, third and fourth columns,
respectively.
* A phase difference is
denoted in terms of the angle formed between the x-axis and a vector whose x-
and y-components are given by the real part and the imaginary part,
respectively, of the arithmetic mean of the cross-spectral densities between
records.
