Interface to produce listings/plots with filtering

This page provides the ability to list (or create a file of) anyselection of the COHO PSP parameters listed below,
only for hours when these and/or other parameters satisfy user-specified numeric ranges.
Click left boxes to select output parameters, and enter desired minimum and/or maximum value(s) in
box(es) to the right of any desired "filtering" parameter(s).
