     "Here, we create a `StructureFactor` object representing the structure factor. We provide the two required keyword arguments: `atoms` we created above, and the maximum spatial frequency `g_max` given in $\\mathrm{Å}^{-1}$ defines the maximum spatial frequency of the structure factor. Increasing `g_max` is equivalent to making the sampling (pixel size) smaller in a multislice simulation. As we describe later on, the $k$-vector of the simulated diffraction patterns, is half that of the structure factor.\n",
