## EICS_OVERLAY_PLOTS

[Next Routine] [List of Routines]

     NAME:
      eics_overlay_plots

     PURPOSE:
      This routine will create a plot of EICS and THEMIS ASI data which is overlaid onto a map of
      the northern hemisphere. See the SECS ASI mosaic overlay plot crib sheet for an explanation of the
      data and how to use this routine. You can find the crib sheet in spedas/projects/secs/examples/

     KEYWORDS:
      trange:        time range of interest
      createpng:     set this flag to create a PNG file of the plot
      showgeo:       set this flag to display geographic latitude and longitude lines
      showmag:       set this flag to display magnetic latitude and longitude lines
      dynscale:      set this flag to use dynamic scaling

     OUTPUT:
      none

     CALLING SEQUENCE:
      eics_overlay_plots, trange=['2017-02-28/00:01:00','2017-02-28/00:02:00'],
          /showgeo, /showmag, /makepng, /dynscale
      See example crib sheets for additional examples

     NOTE: If no time range is specified the routine will use whatever was set previously by timespan or
       timerange.
       If no time has not been set the user will be queried for the time.

    Purpose:
      This routine reads in the EIC ascii data files and creates two tplot variables eic_latlong and
      eic_jxy containing the Equivalent Ionosopheric Currents and the Latitude and Longitude grid

    Keywords:
     PREFIX = STRING      ; String that will be pre-pended to all tplot variable names.
     SUFFIX = STRING      ; String appended to end of each tplot variable created.
     VERBOSE = INTEGER    ; Controls number of informational and error messages displayed
     TPLOTNAMES = STRING ARRAY ; Returns the names of tplot variables
