Table 3

Comparison of the atmospheric parameters of KIC 04749989 obtained by us from the original data and from the LSD-based model spectrum with those reported by Tkachenko et al. (2013, indicated as T2013).

Parameter	Unit	This paper		T2013
		Original	LSD model

T _eff	K	6950 (200)	7380 (130)	7320 (120)
log g	dex	4.02 (45)	4.34 (25)	4.32 (35)
vsini	km s^-1	184 (10)	190 (8)	191 (10)
ξ	km s^-1	2^*	2^*	2^*
[M/H]	dex	+0.12 (12)	–0.03 (8)	+0.00 (12)

Notes. This last study made use of the H_β profile to put additional constraints on T_eff and log g, and is used here as a reference. Errors of measurement estimated from χ² statistics and represented by 1σ level are given in parentheses in terms of last digits.
