The best way to show the interplay between ARTE and HBGEAN is to show the program tree with the relevant calls.

GEANT will only be activated if the command GEAN is inside the .kumac file - this command is equivalent to a call to KAGEAN. From the flow follows that GEANT input command in the ARTE kumac file which control the physical processes or the geometry implementation must be given in before the activation of GEANT (command GEAN).
