The published version of this article contains two errors. In equation (18), there is a typographical error in the second term; it should read R_circle²R_bead instead of R_circleR_bead². The corrected version of equation (18) reads as follows:

In addition, the y axis of the plot in Fig. 3f was incorrectly scaled. A corrected version of Fig. 3 is shown below. Neither of these errors affects any of the conclusions in the paper, as all calculations were based on the correct power spectrum and the correct version of equation (18). We apologize for any confusion that these errors might have caused.
