Interface to produce averages, standard deviations and, if desired, distribution functions.

This page provides the ability to produce averages, standard deviations and distribution functions for any one of the High Resolution OMNI parameters listed below, only for times when the value of this parameter and/or other parameters satisfy user-specified numeric ranges. Click on left side to specify the parameter to be analyzed. Enter in the rightside boxes desired minimum and/or maximum value(s) of this and/or any other desired filtering parameter(s).
