Schematic of the Radial Distribution Function (RDF). The radial distribution function, also known as RDF, g(r), or the pair correlation function, is a measure to determine the
correlation between particles within a system. Specifically, it is a measure of, on average, the probability of finding a particle at a distance of r away from a given reference particle, relative
to that for an ideal gas. The general algorithm involves determining how many particles are within a distance of r and r+dr away from a particle. This general theme is depicted in the schematic,
where the red particle is our reference particle, and blue particles are those which are within the circular shell, dotted in red.
