Eccentricity measurements for a subset of targets from the Kepler EB Catalog. Selections were made in eccentricity error (<0.1) and morphology parameter (<0.5), and measure of signal-to-noise of the intrinsic variability at non-harmonic frequencies (>6). We use the maximum eccentricity as a function of orbital period in Halbwachs et al. (2005, Eq. (3)) with the cut-off period set to 5 and 6.5 days to plot the dashed black and grey lines. Grey points indicate systems that do not belong in this selection or have otherwise faulty measurements.
