Comparison of tested models.
|Model (Period [days])||BIC||ΔBIC||σ o−c|
|[ ms-1 ]|
|K2 (1842, 3.09)||389||221||3.90||2.00|
|K3 (1842, 3.09, 46.7)||275||114||2.47||1.54|
|K4 (1842, 3.09, 46.7, 6.76)||241||34||1.89||1.31|
Notes.The four-Keplerian model is preferred since it has the lowest BIC, and residual dispersion. These values are estimated based on the maximum likelihood.
