Query: Optimal observables and phase-space ambiguities   Optimal observables are known to lead to minimal statistical errors on
parameters for a given normalised event distribution of a physics reaction.
Thereby all statistical correlations are taken into account. Therefore, on the
one hand they are a useful tool to extract values on a set of parameters from
measured data. On the other hand one can calculate the minimal constraints on
these parameters achievable by any data-analysis method for the specific
reaction. In case the final states can be reconstructed without ambiguities
optimal observables have a particularly simple form. We give explicit formulae
for the optimal observables for generic reactions in case of ambiguities in the
reconstruction of the final state and for general parameterisation of the
final-state phase space.
