41 // (Description)
42 // This is a primitive scorer class for scoring only Surface Flux.
43 // Flux version assumes only for G4Sphere shape.
44 //
45 // Surface is defined at the inside of sphere.
46 // Direction -Rmin +Rmax
47 // 0 IN || OUT ->|<- |
48 // 1 IN ->| |
49 // 2 OUT |<- |
50 //
51 // Created: 2005-11-14 Tsukasa ASO, Akinori Kimura.
52 // 29-Mar-2007 T.Aso, Bug fix for momentum direction at outgoing flux.
53 // 2010-07-22 Introduce Unit specification.
54 // 2010-07-22 Add weighted and divideByAre options
55 // 2011-02-21 Get correct momentum direction in Flux_Out.
56 // 2011-09-09 Modify comment in PrintAll().
