radial
------

What it does:  Plots a graph of average intensity vs radial distance along a
               given angle.

Controls:      There are 3 sliders.  The first slider controls the angle at
               which the slice will be taken.  This can also be modified by
               dragging in the main window with the right mouse button.  The 
               second slider controls the thickness of the band, in pixels.
               The third slider controls the number of subdivisions the band
               will be split into.  The position of the earth can be specified
               or modified by dragging in the main window with the left mouse
               button.  Pressing 'go' will create the graph, and will write
               a corresponding postscript file of the same graph in the output
               directory.  The silver band in the middle of the graph indicates
               the region that is over the earth.  The format of the text file
               output by radial is explained in the files themselves as headers
               for the columns of data.

Notes:         None.
