  Only a fraction of all $\Lambda$ and $\bar{\Lambda}$ hyperons detected in
heavy ion collisions are produced from the hot and dense matter directly at the
hadronization. These hyperons are called the {\em primary} hyperons. The rest
of the hyperons are products of the decays of heavier hyperon states, which in
turn are produced at the hadronization. As such, the polarization of only
primary hyperons can be described with the formulae introduced in Sect. 8. For
the rest of the hyperons, the polarization transfer in the decays has to be
computed, and convoluted with the polarization of the mother hyperon. In this
chapter, a derivation of the polarization transfer coefficients, as well as the
computation of the mean polarization of all $\Lambda$ hyperons detected in the
experiment, is presented. The chapter is concluded with the calculation of the
resonance contributions to the global and local $\Lambda$ polarizations.
