Abstract
A main goal of current low background physics is the search for rare and novel phenomena beyond the Standard Model of particle physics, e.g. the scattering off of a potential Dark Matter particle inside a CaWO4 crystal or the neutrinoless double beta decay of Ge nucleus. The success of such searches depends on a reliable background prediction via Monte Carlo simulations. A widely used toolkit to construct these simulations is GEANT4, which offers a wide choice of physics models, so-called physics lists. To facilitate the selection of physics lists for simulations of CaWO4 and Ge targets, we quantify their impact on the total energy deposition for several test cases.

Abbreviation for goodness of fit is used in Conclusions but I do not see this to be introduced earlier.
I suggest to say explicitly in Figure 2 and 3 captions which detector size was used. This is not clear.
