The force exerted by an optical trap on a dielectric bead in a fluid is often found by fitting a Lorentzian to the power spectrum of Brownian motion of the bead in the trap. We present explicit functions of the experimental power spectrum that give the values of the parameters fitted, including error bars and correlations, for the best such x fit in a given frequency range. We use these functions to determine the information content of various parts of the power spectrum, and find, at odds with… CONTINUE READING
