Footnotes

1 It is worth noting that the grain-size effect becomes even more of an issue as the divergence of the instrument is decreased with, for example, high-resolution laboratory or synchrotron-based instruments, since fewer crystallites are likely to meet the diffraction condition.
2 When calculating phase density from crystallographic parameters, a factor of 1.6604 = 1024/6.022 × 1023 is needed to convert ρ in a.m.u. Å−3 to g cm−3.
3 It should be noted that the implementation of the matrix-flushing method by Bish and Howard retains the use of phase density, but their approach is essentially the same as that of Hill and Howard.
