Two long-period transiting exoplanets on eccentric orbits: NGTS-20 b (TOI-5152 b) and TOI-5153 b

Open Access

Table 4

Model comparison based on the log-evidence values (ln Z) for TOI-5153.

	Free eccentricity	Fixed eccentricity
Period aliases	ln Z	ln Z
19.78d	89803.1 ± 0.5	89798.8 ± 0.5
20.33d	89815.5 ± 0.5	89808.7 ± 0.5
20.91 d	89790.2 ± 0.5	89743.0 ± 0.7

Notes. Six fits were performed using a Normal prior on three period aliases around 20 days with the option to set the orbital eccentricity as a free or fixed parameter.
