Period - eccentricity distribution of giant planets: the new CJs presented in this paper are shown as cyan solid circles, while the light red circles represents all giant planets with 0.3 M_J ≤ m (or m sini) ≤ 13 M_J in the Extrasolar Planets Encyclopaedia,. The size of the circles is proportional to their mass (or minimum mass), with this proportion increased by a factor of 5 for the cyan circles to emphasize the newly detected CJs.
