(a) The number of independent observations and (b) the ratio of powder diffraction versus single-crystal observations as a function of reciprocal d spacing (1/d) (Å^-1) and asymmetric unit-cell size (Å³) for a [Delta]

d/d resolution of 10^-4. (c) The number of independent observations and (d) the ratio of powder diffraction versus single-crystal observations as a function of reciprocal d spacing (1/d) (Å^-1) and asymmetric unit-cell size (Å³) for a [Delta]

d/d resolution of 10^-3. Note that an observation will generally consist of multiple Bragg reflections.
