Nov 14, 2000 G. Cosmo - param-V02-00-01
- Moved specific parameterisation models to the new top category
"parameterisations". Moved files:
G4FoamXrayTRmodel[.hh.cc], G4GamDistrXrayTRmodel[.hh.cc],
G4IrregularXrayTRmodel[.hh.cc], G4PAIclusterModel[.hh.cc],
G4PhotoClusterModel[.hh.cc], G4PlateIrrGasXrayTRmodel[.hh.cc],
G4RegularXrayTRmodel[.hh.cc], G4VClusterModel[.hh.cc],
G4VXrayTRmodel[.hh.cc].
- Cleaned-up GNUmakefile of non necessary dependencies.
Aug 03, 2000 G. Cosmo - param-V02-00-00r
- Changed RandGauss to G4RandGauss in G4IrregularXrayTRmodel.cc and
G4VXrayTRmodel.cc to fix events' reproducibility problem.
- G4VXrayTRmodel.cc: fix to class destructor (V.Grichine)
Jun 15, 2000 G. Cosmo - param-V01-01-04
- The tag coworks with global-V01-01-04 and materials-V01-01-00:
o Fixed usage of G4complex type for ISO and non-ISO compilers.
