!! Title: Typical PATHS Output /8:e| ]  
!! Category: Isolated Command L?a4>uVY  
!! Keywords: PATHS, Tracing, stray, ghost \cX9!lHl  
!! Description: Typical output from the PATHS s H'FqV,)  
!! command for all currently defined rays. This &09~ D8f'  
!! output shows the default LONG form and listing H9BqE+  
!! according to total flux. oMM@{Jp  
!! Notes: /'VuMMJ2  
!! 1)  Negative 'Hits' indicate incident rays that 7,?ai6{  
!! either got absorbed by the Current object (typical) Y*lc ~X  
!! or did not go through or interact with current n]w%bKc-9  
!! object (such as with STEP -1). 32j#kJW  
!! 2)  The default LONG form provides for decimal places nip*Y@-F  
!! under Current and Previous headings. This allows I%[Tosud<  
!! for further breakout of paths according to specific pox;NdX7  
!! facets for edge-based objects. oWDn_GnG`h  
!! 3)  Negative 'Split/Scatter' numbers indicate scatter -; d{}F  
!! rays from that object number. Otherwise, they are -`spu)  
!! specular split rays. They are traced back to the source v?nGAn  
!! from left to right (up to 10 levels possible). Refer to sy(bL _%
