Logarithmic Scatter Plot for IMP, Geotail, WIND/FIT/MOM/KP, ACE hourly plasma data, Log. scale

This page provides logarithmic regressions ("logarithmic regression" is shorthand for "linear regressions of logs of parameters") for proton density and temperature, and for alpha to proton density ratios. It gives possibility to cross-normalize these parameters using the results of the logarithmic regressions because they 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) (of logs as appropriate) in relevant box(es) below (more detail).
