HD 1461. Odds ratio for models with n Keplerian curves with respect to models with n−1 Keplerian curves as a function of model complexity n, assuming equal unity prior odds in all cases. The estimates using different techniques are shown and the customary limits for positive (O_{n + 1,n} = 3) and strong (O_{n + 1,n} = 20) and their inverses are shown as dashed and dotted lines, respectively. The model with four signals contains the 620-day Keplerian.
