Specify Lag Number N: from 0(no lag) to 60;
    [N is number of data points by which Y lags X]

Select one of three option below

LRF and scatter plot for lag=N

List data selected for lag=N

LRFs for lags from 0 to N with step M:  (M >= N/10)           [E.g., use M=3 for CC's at lags of 0, 3, 6, ... hours]
