30 // Represents many touchable detector elements differing only in their
31 // positioning. The elements' positions are calculated by means of a simple
32 // linear formula.

34 // G4PVDivision(const G4String& pName,
35 // G4LogicalVolume* pLogical,
36 // G4LogicalVolume* pMother,
37 // const EAxis pAxis,
38 // const G4int nReplicas,
39 // const G4double width,
40 // const G4double offset=0)
41 //
42 // Division may occur along:
43 //
44 // o Cartesian axes (kXAxis,kYAxis,kZAxis)
45 //
46 // The divisions, of specified width have coordinates of
47 // form (-width*(nReplicas-1)*0.5+n*width,0,0) where n=0.. nReplicas-1
48 // for the case of kXAxis, and are unrotated.
49 //
50 // o Radial axis (cylindrical polar) (kRho)
51 //
52 // The divisions are cons/tubs sections, centred on the origin
53 // and are unrotated.
54 // They have radii of width*n+offset to width*(n+1)+offset
55 // where n=0..nReplicas-1
56 //
57 // o Phi axis (cylindrical polar) (kPhi)
58 // The divisions are `phi sections' or wedges, and of cons/tubs form
59 // They have phi of offset+n*width to offset+(n+1)*width where
60 // n=0..nReplicas-1
