41 | // 07-08-01 new methods Store/Retrieve PhysicsTable |
---|
42 | // 23-08-01 new angle and z distribution,energy dependence reduced, |
---|
43 | // Store,Retrieve methods commented out temporarily, L.Urban |
---|
44 | // 11-09-01 G4MultipleScatteringx put as default: G4MultipleScattering |
---|
45 | // Store,Retrieve methods reactived (mma) |

46 | // 13-09-01 Unused TrueToGeomTransformation method deleted, |
---|
47 | // class description (L.Urban) |
---|
48 | // 19-09-01 come back to previous process name msc |
---|
49 | // 17-04-02 NEW angle distribution + boundary algorithm modified, L.Urban |
---|
50 | // 22-04-02 boundary algorithm modified -> important improvement in timing !!!! |

---|
64 | // 05-10-05 value of data member tlimitmin has been changed (L.Urban) |
---|
65 | // 23-10-05 new Boolean data member prec (false ~ 7.1 like, true new step |
---|
66 | // limit in TruePathLengthLimit, L.Urban) |
---|
67 | // 25-10-05 prec renamed to steppingAlgorithm, set function triggers |
---|
68 | // 'default' facrange too, true - 0.02, false - 0.2 (L.Urban) |

75 | // value of facrange (L.Urban) |
---|
76 | // 16-02-06 set function for data member factail (L.Urban) |
---|
77 | // 13-10-06 data member factail removed, new data member skin |

78 | // together with set function, data member tkinlimit |
---|
79 | // changed to lambdalimit (L.Urban) |
---|
80 | // 07-03-07 remove method SetSkin, because it is now in the base class (VI) |
