Uses the sample data set
apjedro4damp02.
Uses the shell scripts
getwfdata and
crosscorr, from our
analysis script archive.
Purpose: to provide a correlation between two time series (2 WFs).
Outcome: Pearson's Product Moment correlation coefficient (r) shows positive, zero or negative correlation. Cross-correlation repeats this test at a number of "lags", shifting one series progressively left or right of the other, to show stability of phase relationships.
Procedure: Rectify and filter ENGs, select data range, downsample data, cross-correlate and plot.
Examples: Combining two cross-correlations on the same graph, creating a cross-correlation histogram figure using Excel.
