   - How is the coordination number $n_1$ defined? Give an analytical formula to compute it from the rdf.   - How is the coordination number $n_1$ defined? Give an analytical formula to compute it from the rdf.
   - Calculate the first coordination number of Na from the Na-O rdf using the script ''./integrate.py %%--%%N=<Natoms> %%--%%L=<BoxLength> < gofr_A_B-X.Y > nc_A_B-X.y'' where ''<Natoms>'' is the number of ''B'' atoms per cell and ''<BoxLength>'' the length of the simulation box in $\unicode{x212B}$.   - Calculate the first coordination number of Na from the Na-O rdf using the script ''./integrate.py %%--%%N=<Natoms> %%--%%L=<BoxLength> < gofr_A_B-X.Y > nc_A_B-X.y'' where ''<Natoms>'' is the number of ''B'' atoms per cell and ''<BoxLength>'' the length of the simulation box in $\unicode{x212B}$.
-  - How does the coordination number of Na with respect to O vary with the constrained Na-Cl distance? What does this mean for the coordination of Na?+  - How does the coordination number of Na with respect to O vary with the constrained Na-Cl distance? What does this mean for the coordination of Na? How to explain the linear increase of Na-O coordination number after 4 angstroms (should be cubic, right?)? (2P)
