Various properties in relation to number of atoms in the sample, with different levels of detector efficiency at 30%, 60%, and 100%. (a) Distance cutoff required. (b) Mean relative angle for all the pairs under the distance cutoff. (c) Number of pairs under the distance cutoff. There seems to be a clear trend for larger distance cutoff, tighter angular restrain, and number of pairs under the distance cutoff with regards to the mass.
