Priors used for fitting distributions in redshift and luminosity bins.
| Model | Morphological parameter | Priors |
|---|---|---|
| Normal | c500, c80 − 800 | μ ∼ 𝒰(−2.2, 0.2), log σ ∼ 𝒰(−1.3, 2.0) |
| ns, 0 | μ ∼ 𝒰(−0.8, 2.8), log σ ∼ 𝒰(−1.3, 2.0) | |
| n50 | μ ∼ 𝒰(−7.7, 0.7), log σ ∼ 𝒰(−1.3, 2.0) | |
| α, α50 | μ ∼ 𝒰(−4.6, 2.6), log σ ∼ 𝒰(−1.3, 2.0) | |
| ϵ, H, M1-M4 | μ ∼ 𝒰(−0.1, 1.1), log σ ∼ 𝒰(−1.3, 2.0) | |
| Skew | All | Same as Normal model, but with additional parameter skew K ∼ 𝒩(0, 10) |
| 2× Normal | All | Two components with normal model priors, plus additional fraction f ∼ 𝒰(0, 1) |
| Interpolated | c500, c80 − 800 | Eight points between −2 and 0, with normalisation Ni ∼ 𝒩(0, 4) on each |
| ns, 0 | Eight points between 0 and 2, with normalisation Ni ∼ 𝒩(0, 4) on each | |
| n50 | Eight points between −4 and −1.5, with normalisation Ni ∼ 𝒩(0, 4) on each | |
| α, α50 | Eight points between −1 and 2, with normalisation Ni ∼ 𝒩(0, 4) on each | |
| ϵ, H, M1 − M4 | Six points between 0 and 1, with normalisation Ni ∼ 𝒩(0, 4) on each | |
Notes. A normal distribution with mean μ and width σ is given as 𝒩(μ, σ). A uniform distribution between a and b is given as 𝒰(a, b). The interpolated model points are separated uniformly in the range specified, with the endpoints at the extreme values.
