| Np | days | 𝒰i(0, 2) |
| P | days | ℒ𝒰(1, Δt) |
| K | m s−1 | ℳℒ𝒰(1, 100) |

Notes. The distributions are abbreviated as follows: 𝒢 = Gaussian with mean and standard deviation; ℳℒ𝒰 = modified log-uniform with knee and upper limit; ℒ𝒰 = log-uniform with lower and upper limits; 𝒰 = uniform with lower and upper limits; 𝒦 = Kumaraswamy with parameters a and b. Pguess and Kguess denote the maximum likelihood estimates for the period and semi-amplitude of the outer companion. Δt is the time span of the time series.
