List of free parameters and respective priors used in the MCMC analysis of the radial velocities.

Parameter Prior

Planet b Planet c
Orbital period P [d]
Epoch of periastron Tp [BJD]
Orbital eccentricity e β(0.867;3.03) β(0.867;3.03)
Argument of periastron ω [°]
Radial-velocity amplitude K [m s-1]

Systemic radial velocity γ [km s-1]
ELODIE radial-velocity jitter [m s-1]
SOPHIE radial-velocity jitter [m s-1]
HARPS radial-velocity jitter [m s-1]
ELODIE – HARPS radial-velocity offset [km s-1]
SOPHIE – HARPS radial-velocity offset [m s-1]

Notes. is a Jeffreys distribution between a and b, is a uniform distribution between a and b, and β(a;b) is a beta distribution with parameters a and b.

Reference. The choice of prior for the orbital eccentricity is described in Kipping (2013).
