PROCEDURE plot_map_sdfit PURPOSE: Draw a fan plot of SD data on the world map :Params: var: tplot variable to be plotted :Keywords: noerase: Set to plot data without erasing the screen clip: Set to scale in to get a magnified map position: Set the location of the plot frame in the plot window center_glat: geographical latitude at which a plot region is centered center_glon: geographical longitude at which a plot region is centered mltlabel: Set to draw the MLT labels every 2 hour lonlab: a latitude from which (toward the poles) the MLT labels are drawn force_scale: Forcibly put a given value in "scale" of map_set geo_plot: Set to plot in the geographical coordinates coast: Set to superpose the world map on the plot nocolorscale: Set to surpress drawing the color scale colorscalepos: Set the position of the color scale in the noraml coordinates. Default: [0.85, 0.1, 0.87, 0.45] pixel_scale: Set a values of range 0.0-1.0 to scale pixels drawn on a 2D map plot :EXAMPLES: plot_map_sdfit, 'sd_hok_vlos_bothscat' plot_map_sdfit, 'sd_hok_vlos_bothscat', center_glat=70., center_glon=180. :Author: Tomo Hori (E-mail: horit at stelab.nagoya-u.ac.jp) :HISTORY: 2011/03/11: Created 2011/06/15: Renamed to plot_map_sdfit
