Normalized density to the density expected for a planet composed 100% of silicates (ρ/ρrock Zeng et al. 2019), stellar host metallicity ([Fe/H]), insolation flux (S), deviation from the expected density of an Earth-like composition (σEarth), spectral type (SpT), and reference papers for all the known planets with Rp < 2R⊕, Mp < 3.5 M⊕, and a mass precision better than 30%.
