Notes. For the Dirichlet SFHs, we selected the prior on log10(sSFR/(yr−1)), but we inferred log10(SFR/(M⊙ yr−1)) instead. Fixed parameters include dust emission, nebular continuum, and emission information. U: Uniform, LU: Log-uniform, and Dir: Dirichlet. † Formed stellar mass (integral of SFH). We also inferred the surviving stellar mass. †† Cosmic times at which 25%, 50%, and 75% of total stellar mass was formed, normalised to the age of the Universe.
