Notes:
The mathematical model described in part I [Urbanowicz (1981). Acta Cryst. A37, 364-368] has been verified by measurements performed on the Bond diffractometer constructed in the author's institute. A computer program has been written allowing the synthesis of the diffraction profile h(ω) for an arbitrary original function f(ω), distribution of tube-focus emissivity is(x), collimator length L2, and for given widths d1, d2 of collimator slits. The calculations have been performed to estimate systematic errors related to the collimation conditions, caused by insufficient accuracy (shift Δs) of the collimator setting in relation to the focus centre and asymmetry function φ of the distribution of tube-focus emissivity. A simplified formula is given for fast estimation of the errors caused by overlapping of the Kα1-Kα2 doublet and by the Lp factor.
