Table 1. Benchmark points with A = 0.1 fixed. Tf is the temperature of the dark sector after the FOPT. α is the strength of the transition, defined by the ratio of the latent heat released and the radiation energy density at the time of the FOPT, and β is the inverse duration of the phase transition. Table 1 is updated to match the benchmark points in the figures. At the bottom of page 7, “Their GW spectra, arising from bubble collisions during the FOPT, . . . ” should read “Their GW spectra, arising from sound waves in the plasma during the FOPT, . . . ”.
