Representation of biased G-, earlyM-, and lateM-pop. X-axes represent the log of the semi-major axis in AU-unit, and the Y-axes represent the log of masses in M_⊕-unit. The coloured dots represent visible planets with radial velocity semi-amplitudes exceeding the threshold, while the grey dots represent invisible planets with radial velocity semi-amplitudes below the threshold. The green boxes represent the definition of an ELP adopted in this study.
