Same as Fig. 3, but the colour of the symbols indicates the mass of the planet. The dashed black lines indicate the loci where n = Ω and n = 2Ω as labelled. The solid black line is, for a given orbit, the contribution of the orbital angular momentum to the total momentum. The solid coloured lines are the best fits for the stationary locus for planets with M_p ≤ 1M_J orbiting either stars with T_eff ≥ 6250 or T_eff< 6000 K. Their colours correspond to the average planetary mass of the respective subsamples. The 90% confidence interval is given by the dotted lines of the respective colours.
