Interface to produce averages, standard deviations and, if desired, distribution functions for STEREO-A.

ABOUT THE DATA

This page provides the ability to produce averages, standard deviations and distribution functions for any one of parameters 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).
