20 Correlation Functions

The CORREL command is used to obtain a time series for a given property (`correlation-spec') and then manipulate it as required (`manip-spec') to plot the time series , correlation function, spectral density, etc. and determine the correlation times.

Reorienting a coordinate trajectory is possible using the COMPARE command. For details, see Reorienting a Coordinate Trajectory.

N.B.: The documentation for correlation functions is not in the best of shape. Until there is an opportunity to go through all of the code and associated documentation in order to verify its accuracy, please use this command with especial care. Don't put all your faith in what you are about to read.
