PRO: THM_LSP_REMOVE_SPIKES NOT FOR GENERAL USE. ONLY FOR ISOLATED PARTICLE OR WAVE BURSTS NOT FOR ENTIRE ORBIT. PURPOSE: Remove the non-physical spiky signals in the efw data. INPUT: t -NEEDED. Time array Ex, Ey, Ez -NEEDED. Data. Leave blank or set to zero to skip. per -NEEDED. Spin period. Efp -NEEDED for wave burst. Not needed for particle burst. KEYWORD: nwin -OPTIONAL. Number of points in spike search window. DFLT = 16 spikesig -OPTIONAL. Sigma of spikes. DFLT = 5 sigmin -OPTIONAL. Minimun of sigma. DFLT = 0 mV/m. nfit -OPTIONAL. Number of points in the fit window. DFLT = 16 fit -OPTIONAL. If set, will fit spikes to Gaussian. DFLT = 0 HISTORY: 2009-05-12: REE. Complete rewrite for wave burst. VERSION: $LastChangedBy$ $LastChangedDate$ $LastChangedRevision$ $URL$
