!! Title: Typical PATHS Output D2Go,1  
!! Category: Isolated Command z:R2Wksg  
!! Keywords: PATHS, Tracing, stray, ghost et]*5Y6  
!! Description: Typical output from the PATHS \>/:@4oK  
!! command for all currently defined rays. This Sb[rSczS~  
!! output shows the default LONG form and listing #(*WxVE  
!! according to total flux. Fk(0q/b  
!! Notes: (^Do#3  
!! 1)  Negative 'Hits' indicate incident rays that Lou4M  
!! either got absorbed by the Current object (typical) {nOK*7+ "  
!! or did not go through or interact with current [I4FU7mpH  
!! object (such as with STEP -1). %dT%r=%Y  
!! 2)  The default LONG form provides for decimal places v981nJ>w,  
!! under Current and Previous headings. This allows |_2ANWHz  
!! for further breakout of paths according to specific IL:"]`f*  
!! facets for edge-based objects. *Ucyxpu~$  
!! 3)  Negative 'Split/Scatter' numbers indicate scatter O x$|ZEh  
!! rays from that object number. Otherwise, they are O\KAvoQ%s  
!! specular split rays. They are traced back to the source [Iihk5TT  
!! from left to right (up to 10 levels possible). Refer to iK %Rq
