OMNIWeb Data Explorer - Near-Earth Heliosphere Data - NSSDC - Goddard Space Flight Center

For Linear Regression Fits (LRF) and scatter plots for single lag (including zero lag) and
for LRF for series of lags, for auto- and cross-correlation functions.

* About using this interface

* 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:  (N/M <= 10)   
    [Step number M is incremental number of data points for successive lags]

*Select resolution
     1-min averaged 5-min averaged
