  • Effective temperature entered under equilibrium temperature; planet mass entered as range across several different models. (Keppler et al. 2018)
  • Uncertainties for semimajor axis, orbital eccentricity, orbital inclination, longitude of periastron, equilibrium temperature, planet radius have been re-scaled to 1-sigma. (Wang et al. 2020)
  • Selected the Table 3 parameters corresponding to the Dynamically Stable solution. (Wang et al. 2021)
  • Effective temperature entered under equilibrium temperature. (Wang et al. 2021)
PDS 70 c
  • Planet mass value/uncertainties estimated from range given in ref. (Haffert et al. 2019)
  • Uncertainties for semimajor axis, orbital eccentricity, orbital inclination, longitude of periastron, equilibrium temperature, planet radius have been re-scaled to 1-sigma. (Wang et al. 2020)
  • Selected the Table 3 parameters corresponding to the Dynamically Stable solution. (Wang et al. 2021)
  • Effective temperature entered under equilibrium temperature. (Wang et al. 2021)
