Free parameters and their associated prior distribution functions in the Prospector physical model.
| Parameter | Description | Prior distribution |
|---|---|---|
| log (M⋆/M⊙) | Total stellar mass formed | Uniform: min = 7, max = 12 |
| log (Z⋆/Z⊙) | Stellar metallicity | Uniform: min = −1.98, max = 0.4 |
| SFR ratios | Ratio of adjacent SFRs in the eight-bin nonparametric SFH, seven free parameters in total | Student’s t-distribution with σ = 0.3 and v = 1 |
| log (Zgas/Z⊙) | Gas-phase metallicity | Uniform: min = −2, max = 0.5 |
| z | Redshift | Fixed to LEGA-C spectroscopic redshift |
 |
Diffuse dust optical depth | Clipped normal: min = 0, max = 4, mean = 0.3, σ = 1 |
 |
Birth-cloud dust optical depth | Clipped normal in ( ): min = 0, max = 4, mean = 0.3, σ = 1 |
| n | Slope of Kriek & Conroy (2013) dust law | Uniform: min = −1, max = 0.4 |
