     6== Function == 
     7Takes data from one or more waveservers, computes and processes their spectra.

     9== Details == 
     10The ewspectra module takes data from one or more waveservers, can perform a variety of operations on that data, most importantly computing an FFT and identifying the frequencies w/ the highest amplitudes in the resulting spectra. Results can be written to files in a specified directory or as messages to a ring. Specification of the timespans to process can be specified in the configuration file and/or via messages read from a ring.

     12The primary option is what SCNLs to monitor and, if 2 are specified, how to combine them: 
     13 
     14 * A single SCNL is specified & its spectra computed 
     15 * 2 SCNLs are specified and the difference between their spectra is computed 
     16 * 2 SCNLs are specified, and their spectra are deconvolved 
     17 
     18Other options include tapering of the original timeseries, applying high- and/or low-pass Butterworth filters, and smoothing the spectra before writing.
