Overview:

Plots a graph of average intensity vs radial distance along a given angle.

How to use:

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.
