PROCEDURE/FUNCTION sd_map_set :DESCRIPTION: A wrapper routine for the IDL original "map_set" enabling some annotations regarding the visualization of SD data. :PARAMS: time: time (in double Unix time) for which the magnetic local time for the world map is calculated. In AACGM plots, the magnetic local noon comes on top in plot. :KEYWORDS: erase: set to erase pre-existing graphics on the plot window. clip: set to zoom in roughly to a region encompassing a field of view of one radar. Actually 30e+6 (clip is on) or 50e+6 (off) is put is "scale" keyword of map_set. position: gives the position of a plot panel on the plot window as the normal coordinates. center_glat: geographical latitude at which a plot region is centered. center_glon: geographical longitude at which a plot region is centered. (both center_glat and center_glon should be given, otherwise ignored) 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. stereo: Use the stereographic projection, instead of satellite projection (default) nogrid: Set to prevent from drawing the lat-lon mesh twohourmltgrid: Set to draw the MLT lines for every other hour, instead of every hour (default) :EXAMPLES: sd_map_set sd_map_set, /clip, center_glat=70., center_glon=180., /mltlabel, lonlab=74. :AUTHOR: Tomo Hori (E-mail: horit@stelab.nagoya-u.ac.jp) :HISTORY: 2011/01/11: Created $LastChangedBy: jwl $ $LastChangedDate: 2014-02-10 16:54:11 -0800 (Mon, 10 Feb 2014) $ $LastChangedRevision: 14265 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/erg/ground/radar/superdarn/sd_map_set.pro $
