✦ Synopsis

When calculating the average course of the decay of RF-spoiled SSFP sequences (red curves in Fig. 9c andd), the integration contour not only enclosed the singularities on the real positive axis (red line in Fig. 9b) but, accidentally, also the two adjacent complex conjugate end points of the green cut lines. Due to their small but nonzero phase, the latter added low-frequency oscillations to the decay, which perfectly reproduced the observed nonexponential behavior, but were erroneously attributed to and explained with the dispersion of real valued singularities (Fig. 10). Taking account of that, no further changes to the article are necessary.

The author regrets this oversight.
