FUNCTION: THM_LSP_NOTCH_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 x -NEEDED. Data per -NEEDED. Spin period. tpks -NEEDED. Phase of spikes. KEYWORD: nfit -OPTIONAL. Number of points in the fit window. DFLT = 16 (256 for wave) fit -OPTIONAL. If set, will perform a Gauss fit. Amp -OPTIONAL. Estimated amplitudes. Same number of elements as tpks. Diagnose -OPTIONAL. Plots fits and notchs. Talk -OPTIONAL. Indicates number of fits and notchs. HISTORY: 2009-05-30: REE. Broke out to run with wave burst.
