The temperature dependence of the ratio [\sum^{N/2} I_{\rm odd}/\sum^N I_{\rm all}], where [\sum^{N/2} I_{\rm odd}] is the sum of the intensities of reflections extinguished by the Bravais cell I, for which sums of Miller indices h + k + l are odd, and [\sum^N I_{\rm all}] is the sum of all measured intensities. The sums include negative intensities to avoid zero-intensity bias and only full data sets, measured at 123, 180, 225 and 235 K, have been used. The values obtained are: 0.16215 (7), 0.15074 (13), 0.11330 (8) and 0.05861 (4), respectively; the standard deviations have been calculated by the method of total differential basing on the counting statistics of the intensity measurements.
