Analysis of data obtained from the two twins in the P21 crystal form. (a) The percentage of reflections that are not affected by overlap or partial overlap depends on the orientation of the twinned crystal in the beam. Data were collected with a 0.5° oscillation range. (b) Resolution-dependence of the signal-to-noise ratio for the data sets of the two twins. (c) Resolution-dependence of the apparent twin fraction (TF), with TF = 〈I(h′)〉/[〈I(hkl)〉 + 〈I(h′k′l′)〉], where 〈I(h)〉 and 〈I(h′)〉 are the mean intensities for twin 1 and 2, respectively.
