PROCEDURE: thm_crib_tplot_overlay ***** A copy and paste crib ***** PURPOSE: A crib showing how to overlay spectra on top of spectra. DETAILS This crib shows how to combine full and burst mode spectra into one plot by overlaying the burst mode data on top of the full mode data. The DATAGAP keyword is very useful when you want to overlay burst mode spectra plots over full mode spectra. Set the DATAGAP keyword to a number of seconds that is less than the time gap of the burst data, but greater than the sample interval of the underlying full mode data. This way the time gaps between the burst mode data won't be interpolated by SPECPLOT and cover up the full mode data between the burst mode data. CREATED BY: Bryan Kerr
