They are described by O information system restricted states R formalism by Breuer and can be obtained also in Algebraic QM considering Segal Algebra of O observables. From Segal theorem it's shown that R describes the random measurement outcomes in the individual events.10 pages, Proc of Vienna Quantum Structures ConferenceQuantum Physicstext
