!! Keywords: PATHS, Tracing, stray, ghost K&TO8   
!! Description: Typical output from the PATHS {M P (*N

!! output shows the default LONG form and listing G q2@37U  
!! according to total flux. 0z`-fQfK  
!! Notes: #;F*rJ[XY  
!! 1)  Negative 'Hits' indicate incident rays that ;&ypvKG

!! or did not go through or interact with current -=a,FDeR  
!! object (such as with STEP -1). !9vq"J~hz"  
!! 2)  The default LONG form provides for decimal places \'-E[xNcWI  
!! under Current and Previous headings. This allows m-MfFEZ  
!! for further breakout of paths according to specific o$KW*aDp  
!! facets for edge-based objects. @Avve8S  
!! 3)  Negative 'Split/Scatter' numbers indicate scatter K)s{D ] B  
!! rays from that object number. Otherwise, they are <@J0 770  
!! specular split rays. They are traced back to the source Gq0`VHAn  
!! from left to right (up to 10 levels possible). Refer to 7~m[:Eg6[s
