hard spheres all defined by 𝜎 (convention used by RASPA2 to calculate surface areas). If we compare simulation with 𝜆 = 1, we obtain surface areas that are very close to the one obtained by RASPA2 (see Figure in SI). However, when we consider 𝜆 = 1.6, we lose the perfect accordance previously obtained and the points weakly correlated in log-scale (see Figure in SI). The difference can be explained by the fact that the sphere size is larger, but the proportion of adsorbable points also changes. The relationship between these two adsorption surface areas is no trivial at all. Since the calculation of surface areas is quite cheap, this implementation would not be very useful, except for having a rough idea of the surface area.
