... The fit to the radial-velocities gives a reduced χ2r = 0.75 ± 0.17, suggesting we may have overestimated our error bars on the measurements. The largest contribution to the χ2 comes from the second point in the HARPS Rossiter-McLaughlin series, likely affected by high seeing. No eccentricity can be d ...
