Comparison of the dose enhancement ratios (DER) for the narrow beam used in the simulations in [26] and for an extended photon field under secondary particle equilibrium for (a) a 50 nm GNP and 50 kVp X-rays, (b) a 50 nm GNP and 100 kVp X-rays, (c) a 100 nm GNP and 50 kVp X-rays and (d) a 100 nm GNP and 100 kVp X-rays. The different symbols correspond to the different participants in the exercise. Open symbols indicate that the reported simulation results did not pass the plausibility checks and no explanation could be reported by the participant. The other data sets passed the plausibility tests, where in some cases identified normalization issues have been corrected for. A hashtag on the participant identifier indicates that a fluence correction was applied on the data (as the photon source geometry was at variance with the exercise definition). A percent sign indicates that results from revised simulations are shown. In both cases, the respective results for the narrow beam differ from those shown in Fig. 4 of [26].
