Description frank.gaede 2005-11-23 09:23:38 CET

Most geant4 hadronics physics lists reqire the photon evaporation data files to
be present, i.e. the environment variable $G4LEVELGAMMA has to be set.
However the program will not issue a warning if the data files are not actually
there. Instead it will sillently carry on. This is a problem, e.g. in
distributed computing environments where a resource might temporarily not be
available and the user has no way of knowing that something actually went wrong.

A warning is now in place which will indicate that a gamma levels file for
a particular nuclide is missing.  The program will keep running, but no
gammas will be produced.  When G4LEVELGAMMADATA has been set correctly, there
may still be missing files due to a lack of data for rare fission fragments,
for example.
