Scatter Plots for Bow Shock Parameters
This interface enables users to generate scatter plots of any one of a subset of the parameters in the bow shock database against any other parameter of the subset, for only that subset of crossings in which the values of any user-specified combination of parameters satisfy user-specified numeric ranges.

An obvious application is to plot the (X,Y) values of the crossings for selected ranges of Z and any other parameters (e.g., flow pressure).

Descriptions of all the words are available from the main bow shock page.
