Figure 9: The smallest fraction of black hole mass in ringdown waveforms that is needed to observe the fundamental mode at a distance of 3 Gpc (left) for three values of the black hole spin, j = 0 (solid line) j = 0.80 (dashed line) and j = 0.98 (dot-dashed line) and the error in the measurement of the various parameters as a function of the black hole spin for the same mode (right).
