I am trying to use the waveform cross-correlation subroutine "crscor"
provided in lib/libsac.a in a Fortran code (see file correlatef.f in
doc/examples for details).
When the number of windows is more than 1, can somebody please confirm
whether it returns the sum of cross-correlations of all windows or the
mean/average cross-correlation of all windows, i.e. does it divide the
sum of cross-correlations of all windows by the number of windows ?
