PSTAR stopping data are of G4BraggModel. There is no possibility to use alternative data sets for proton stopping power by G4BraggModel but potentially possible to replace this model but an alternative one. We do not provide possibility easy replacing of this data because there were no requirements from users, moreover all tests until now demonstrate that Bragg peak position for proton beam is accurate.
So, if know accurate data which cannot be reproduced by standard Geant4 stopping you may try out a custom alternative model replacing G4BraggModel and also it is possible to replace G4BetheBlochModel.
