Extended Data Table 2 Summary of our SED parameters

From: The onset of star formation 250 million years after the Big Bang

  1. In single-component models, three SFHs with constant, exponentially declining and exponentially rising SFRs are considered. In two-components models, constant SFHs with star formation durations of τ = 10 Myr, 10 Myr, 200 Myr, 300 Myr and 400 Myr are used for the old component (see Extended Data Fig. 4). The parameter fSFR0 defines the SFR ratio of the two components at the observation (z = 9.1). In all models, dust attenuation steps are ΔAV = 0.1 and age intervals follow the original 36 steps in GALEXEV48, at 0.1–550 Myr. The SFR ratio steps are Δlog(fSFR0) = 0.1. The metallicity value of 0.02 corresponds to the solar metallicity.
