The several pathways correspond to various functionalities, including: plotting and listing user-specified (u-s) subsets of parameters for u-s time spans and, for spacecraft-specific data, for u-s spacecraft combinations; scatter plots and linear regression analysis for any pair of parameters; distribution functions, medians and means and their standard deviations; ftp downloads. Most pathways allow filtering of the data analyzed by ranges of parameters being analyzed or of other parameters. Most of these interfaces have their own "About using this interface" option to help users if needed.
The data included and their preparation are extensively discussed
