Notes.
The truncated Gaussian distributions are truncated at ±3σ, i.e., solutions are rejected beyond this limit.
θ is the limb-darkened angular diameter (Defrère et al. 2012). This error is obtained as the quadratic sum of the statistical and systematic errors given in Defrère et al. (2012).
This is deduced from the value of Mbol rather than L provided in Crifo et al. (1997), and assuming it has the same uncertainty as Mv.
The following values and errors were used in this average: 7995 K (Saffe et al. 2008, using the calibration of Castelli et al. 1997), 8035 ± 74 K (Zorec & Royer 2012), 8045 ± 97 K (Blackwell & Lynas-Gray 1998), 8052 K (Gray et al. 2006), 8084 K (Schröder et al. 2009), 8128 K (Allende Prieto & Lambert 1999), 8157 K (Saffe et al. 2008, using the calibration of Napiwotzki et al. 1993), 8200 K (Holweger & Rentzsch-Holm 1995), 8230 ± 350 K (Sokolov 1995), 8300 ± 282 K (David & Hillenbrand 2015), 8500 K (Mittal et al. 2015), 8543 K (da Silva et al. 2009).
