;+ ; SECS ASI mosaic overlay plot crib sheet ; ; ASI (All Sky Imager) from THEMIS mission ; SECS (Spherical Elementary Currents) data has two data types ; EICS (Equivalent Ionospheric Currents) are the horizontal currents and ; SECA (SEC Amplitudes) are the current amplitudes ; ; Data resolution is 1 minute. Note: Datasets are large. It's recommended smaller time ; ranges be used ; ; The ground based magnetometer stations used to derive the data are available for some dates. ; ; The SECS archive is created and maintained by James Weygand ; ; All data are available at http://vmo.igpp.ucla.edu ; ; do you have suggestions for this crib sheet? ; please send them to clrussell@igpp.ucla.edu ; ;- timespan, '2015-03-23' tr=timerange() ; plot the EICs data on top of the ASI mosaic plot eics_overlay_plots, trange=tr stop ; plot the SECa data on top of the ASI mosaic plot (note if timespan is used ; to set the timerange you do not need to use the trange keyword) seca_overlay_plots, trange=tr stop ; create png file (the /createpng keyword is available for both eics and seca plots) ; PNG file format: C:\data\secs\Mosaic/yyyy/mm/dd/ThemisMosaicEICSyyyymmdd_hhmmss eics_overlay_plots, trange=tr, /createpng stop ; you can turn off either geo or the mag grid lines by using showgeo and showmag keywords seca_overlay_plots, trange=tr, /showgeo, /showmag stop ; for days that have ground based station information the stations will automatically be ; plotted as well. Station locations are displayed as green stars. timespan, '2008-03-09' eics_overlay_plots, /showgeo print, 'done' end
