Summarized star-formation histories of our z > 3 quiescent galaxies. Galaxies are sorted by descending redshift, and are each displayed on a separate line. The black vertical bar indicates the redshift at which the galaxy is observed. The orange and blue bands show the 90% confidence range for the quenching and formation redshifts, respectively. Bars of darker colors indicate the corresponding best fit values. These values are listed in Table 3.
