Remarks: All mass values were shortened to appropriate decimals and partly rounded to halves or integers of a Jupiter mass. ^a Hot-start models.
^bNon irradiated models. ^c Using $M_{K{\rm s}}$ = 14.05 $\pm$ 0.08 mag (Marois et al. 2008). ^d Using $M_{K{\rm s}}\sim$ 13.12 mag instead of slightly different values $M_{K{\rm s}}$ = 13.13 $\pm$ 0.08 mag for HR 8799 c and $M_{K{\rm s}}$ = 13.11 $\pm$ 0.12 mag for HR 8799 d, given in Marois et al. (2008).
