    "abstract": "We study the dynamics of classical and quantum systems undergoing a\ncontinuous measurement of position by schematizing the measurement apparatus\nwith an infinite set of harmonic oscillators at finite temperature linearly\ncoupled to the measured system. Selective and nonselective measurement\nprocesses are then introduced according to a selection of or an average over\nall possible initial configurations of the measurement apparatus. At quantum\nlevel, the selective processes are described by a nonlinear stochastic\nSchr\\\"odinger equation whose solutions evolve into properly defined coherent\nstates in the case of linear systems. For arbitrary measured systems, classical\nbehavior is always recovered in the macroscopic limit.",
