Notes. Orbital elements are given as the date 110.5394 [BJD-2454833.0]. The main value is the median of the posterior distribution. The reported errors are the distance to the 0.15865 quantile (lower error) and 0.84135 quantile (upper error). U refers to a flat prior between the given bounds, while 𝒩(µ, σ) refers to a Gaussian distribution of mean µ and standard deviation σ. U*: For the k = e cos ϖ and h = e sin ϖ variables, an additional prior was added to enforce a uniform distribution for their module e. f/d indicates that the variable is fitted for the circular model, but derived in the n-body model (where λj is the fitted parameter). The reported S/N is the median depth of transit over its standard deviation to better account for potential degeneracy with the noise modelling at the transit location.
