Logarithmic Scatter Plot IMP, WIND, ACE, Geotail hourly plasma data
This page provides logarithmic regressions ("logarithmic regression" is shorthand for "linear regressions of logs of parameters") for density and temperature. It gives possibility to cross-normalize densities and temperatures using the results of the logarithmic regressions because densities and temperatures tend to be more log-normally distributed than linearly distributed.

To generate scatter plots and regression fits specify: plot or list (retrieve); time span; X and Y;(optional) filter(s).
Filter against any parameter(s) on screen by specifying min and/or max value(s) in relevant box(es) below (more detail).
