The empirical determination of the correction coefficients makes it possible to include into their values all actual changes in the measuring technique which affect the correction. It is neither necessary nor favourable to use all matrix elements for the correction. Therefore, selection criteria are given which allow arrangement of the matrix elements according to their importance to the correction. The correction strategy is described with the aid of two practical examples: a good agreement is found between theory and practice.
