59 * @class BondOrderParameter
60 * @brief Bond Order Parameter
61 *
62 * Computes orientational bond order parameters as outlined in:
63 *
64 * "Bond-orientaional order in liquids and glasses," by
65 * P. J. Steinhart, D. R. Nelson, and M. Ronchetti,
66 * Phys. Rev. B, 28, 784 (1983).
67 *
68 * A somewhat more useful reference which has formulae for these order
69 * parameters for individual atoms is:
70 *
71 * "Numerical calculation of the rate of crystal nucleation in a
72 * Lennard-Jones system at moderate undercooling," by
73 * Pieter Rein ten Wolde, Maria J. Ruiz-Montero, and Daan Frenkel,
74 * J. Chem. Phys. 104, pp. 9932-9947 (1996).
75 *
76 * Note that this version uses a single cutoff radius to decide
77 * membership in the list of neighbors, and does not have use a
78 * distance-dependent weighting as used in the second reference above.
79 *
80 * The selection script can be utilized to look at specific types of
81 * central atoms. A dynamic selector can also be utilized. By default,
82 * this class computes the Q_{l} and \hat{W}_{l} parameters up to l = 12.
83 * The completed configurational averages of these values as
84 * well as the distributions of atomic q_{l} and \hat{w}_{l} values
85 * are then placed in .boq and .bow files.
