Abstract

In the preceding reference [CKMZ] we have shown how the fundamental gaugino and higgsino parameters of the chargino and neutralino system in supersymmetric theories can be determined in high--precision experiments at $e^+e^-$ linear colliders. Within the Minimal Supersymmetric Standard Model these parameters can be reconstructed completely even if only the light charginos $\tilde{\chi}^\pm_1$ and the light neutralinos $\tilde{\chi}^0_1$ and $\tilde{\chi}^0_2$ are kinematically accessible in the initial phase of these machines, as demonstrated in this Addendum.
