CLUSTER WBD Spectrogram Plotting

This application uses IDL procedures to apply FFT spectral analysis to Cluster WBD waveform data and produce a plot consisting of up to four panels for four spacecraft.

Common Specification

These input and processing selections are common to all panels. Be sure to verify available spacecraft modes for a given time range.
