Notes. The first five passbands and their non-linear limb-darkening coefficients were chosen to match those from Sing et al. (2011b), while the last three match those from Pont et al. (2008). The coefficients for the entire HARPS range were taken from Triaud et al. (2009) for a quadratic limb-darkening law. We note that order 97 (central wavelength λ = 631.06 nm) was strongly affected by telluric molecular oxygen absorption and was therefore removed from the analysis.
