41 // (Description)
42 // This is a primitive scorer class for scoring Surface Flux.
43 // Current version assumes only for G4Box shape, and the surface
44 // is fixed on -Z plane.
45 //
46 // Surface is defined at the -Z surface.
47 // Direction -Z +Z
48 // 0 IN || OUT ->|<- |
49 // 1 IN ->| |
50 // 2 OUT |<- |
51 //
52 // Created: 2005-11-14 Tsukasa ASO, Akinori Kimura.
53 //
54 // 18-Nov-2005 T.Aso, To use always positive value for anglefactor.
55 // 29-Mar-2007 T.Aso, Bug fix for momentum direction at outgoing flux.
56 // 2010-07-22 Introduce Unit specification.
57 // 2010-07-22 Add weighted and divideByAre options
