Interface to produce averages, standard deviations and, if desired, distribution functions for Parker Solar Probe (PSP).

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