Notes. The reference parameter sample of well-studied FGK stars used for the tests reported in this work. The errors of V-mag are 0.01 mag. KIC 12069424 is 16 Cyg A and KIC 12069449 is 16 Cyg B. See Sect. 2.2 for a more detailed description. v sin i values are not tabulated here however they range from 1.1 km s⁻¹ (α Cen B) to 12.7 km s⁻¹ (η Boo). The Ks magnitudes are taken from Cutri et al. (2003), except for the stars marked in the table, for which they were calculated from K magnitudes taken from the following references, transformed to Ks using Eq. (A.1) from Carpenter (2001): ^(a)Engels et al. (1981), ^(b)Glass (1974), Engels et al. (1981), Carter (1990), ^(c)Johnson et al. (1966, 1968), Aumann & Probst (1991), ^(d)Johnson et al. (1966), Johnson (1967), Blackwell et al. (1979), Ghosh et al. (1984), Selby et al. (1988), Arribas & Martinez Roger (1989), ^(e)Low & Johnson (1964), Johnson et al. (1966), Glass (1974), Veeder et al. (1978), Engels et al. (1981), Tapia et al. (1984), Roth et al. (1984), Evans et al. (1987), Alonso et al. (1994). The photo-geometric distances of the stars are taken from Bailer-Jones et al. (2021), these use Gaia EDR3 parallaxes which are not marked in the table (Gaia Collaboration 2020). The stars that are marked, the distances were calculated using the formula d = 1/π and thus parallaxes shown are from ⁽¹⁾Gaia Collaboration (2020), ⁽²⁾van Leeuwen (2007), ⁽³⁾Pourbaix & Boffin (2016). Mean and standard deviation are given in cases where there is more than one reference. All parameters that have an uncertainty of 0.00 are accurate to less than 0.00 of the given unit. The current solar effective temperature is 5772 ± 1 K (Prša et al. 2016), and the use of the older value of 5777 K within this study is justified by the SAPP systematic uncertainties which are more than 10 K.
