在example中的PATHS例子中 A6TNtXk

!! Title: Typical PATHS Output RX7,z.9@'O  
!! Category: Isolated Command c @2s!bs  
!! Keywords: PATHS, Tracing, stray, ghost Dugr{Y/0  
!! Description: Typical output from the PATHS e:NzpzI"v  
!! command for all currently defined rays. This mQo]k  
!! output shows the default LONG form and listing oBAD4qK  
!! according to total flux. *k=Pk  
!! Notes: )9L1WOGi  
!! 1)  Negative 'Hits' indicate incident rays that P`V#Wj4\  
!! either got absorbed by the Current object (typical) VpTp*[8O  
!! or did not go through or interact with current ^[^uDE <  
!! object (such as with STEP -1). Bv3?WW  
!! 2)  The default LONG form provides for decimal places s&8QRI.  
!! under Current and Previous headings. This allows *K-,<hJ#L  
!! for further breakout of paths according to specific 4vE,nx=  
!! facets for edge-based objects. s{< rc>  
!! 3)  Negative 'Split/Scatter' numbers indicate scatter 4s0>QD$J  
!! rays from that object number. Otherwise, they are Q0ev*MS9Z  
!! specular split rays. They are traced back to the source {PYN3\N,  
!! from left to right (up to 10 levels possible). Refer to X$PT-~!a
