Motion of the sources. Gray arrows show the projected motion of the burst component in frequency as the burst drifts in frequency given by the color bar. Centroid positions as a function of time for fundamental (red) and harmonic (blue) components with time after the peak at each frequency (Fig. 4). The error bars represent one standard deviation of uncertainty. The uncertainties of the position determined by the 2D Gaussian fit (Methods section) are given by the red and blue crosses
