Overview of the 12 models applied to RVs and activity indicators in this study.

Model	GP dimension	Orbital eccentricity	Long-term trend	Activity indicator	GP kernel
a	0	Circular	No trend	None	None
b	0	Circular	Linear trend	None	None
c	0	Circular	Quadratic trend	None	None
d	0	Eccentric	No trend	None	None
e	0	Beta distribution	No trend	None	None
f	1	Circular	No trend	None	Quasi-Periodic
g	1	Eeccentric	No trend	None	Quasi-Periodic
h	2	Circular	No trend	FWHM	Quasi-Periodic
j	2	Eccentric	No trend	FWHM	Quasi-Periodic
k	3	Circular	No trend	FWHM+BIS	Quasi-Periodic
m	3	Eccentric	No trend	FWHM+BIS	Quasi-Periodic
n	3	Beta distribution	No trend	FWHM+BIS	Quasi-Periodic

Notes. Each row represents a single model, with the columns indicating the choices made for that model. Note: we do not label models as i or 1 to avoid confusion with the number 1.
