Bayesian model comparison of different noise models for HD 96700.
HD 96700 | Number of planets | ||||
---|---|---|---|---|---|
Model | 0 | 1 | 2 | 3 | 4 |
Base | − 130.5 ± 0.2 | − 59.0 ± 1.6 | − 10.3 ± 0.8 | 0.0 ± 0.9 | − 1.0 ± 2.8 |
FF’ | − 136.7 ± 0.5 | − 64.3 ± 1.4 | − 9.7 ± 1.6 | − 13.3 ± 1.5 | |
Correlated noise | − 115.3 ± 0.1 | − 38 ± 3.5 | + 6.6 ± 1.7 | + 6.88 ± 1.4 | + 6.1 ± 1.2 |
Notes. The Base model contains only keplerians and Gaussian white noise, FF’ is modeled following Aigrain et al. (2012) and the Correlated Noise model includes a quasi-periodic kernel in the covariance matrix. All evidence values are reported relative to the evidence of the base model with 3 planets.
