!! Title: Ghost Analysis Showing Multiple Paths
!! Category: Simple Problem
!! Keywords: Lenses, ghost, LENSES, triplet, SPREAD, COLENGTH, PATHS, HISTORY !! Description: A Triplet lens system is used to demonstrate
!! real ghost image analysis. Initially a plot of the lens system
!! is shown with an on-axis and off-axis source. Then SPLIT
!! is set to 2 and a single source is traced.
!! Children and grandchildren rays are produced and generate
!! alternate paths to the target. A spread function of
!! imaged and ghost rays is performed showing radial
!! distance using THE COLENGTH modifier or by SHAPEing the
!! ghost rays first. Finally, individual ghost paths are traced
!! using SAVEd HISTORY file.
