Errors in the measurement of integrated intensity with a single-crystal diffractometer using non-monochromatic radiation are determined by: (i) the magnitude of the scan volume in reciprocal space, (ii) variation in truncation of the region around the reciprocal lattice points, (iii) incorrect determination of the background. The most accurate results are likely to be obtained by the use of suitable scanning procedure with the appropriate filters, combined with the correct estimation of aperture dimensions and their inclination.
