    "abstract": "Notions of robust and \"classical\" states for an open quantum system are\nintroduced and discussed in the framework of the isometric-sweeping\ndecomposition of trace class operators. Using the predictability sieve proposed\nby Zurek, ``quasi-classical\u0027\u0027 states are defined. A number of examples\nillustrating how the ``quasi-classical\u0027\u0027 states correspond to classical points\nin phase space connected with the measuring apparatus are presented.",
