Comparison of modeled and observed NGA curves of 67P/C-G. Left panel: NGA of 67P/C-G in the terrestrial equatorial frame, evaluated under the dust layer removal model composed of 0.6 mm particles and a porosity of 0.6. Right panel: Fig. 2 from Kramer & Läuter (2019), showing the observed NGA (top) and the Marsden model simulation (bottom). Both panels are plotted on the same vertical scale for direct comparison.
