Notes. (a)[Fe / H] = −0.09 ± 0.03 dex, and fixed vt = 1.41 km / s, vmac = 4.55 km / s. (b)[Fe / H] = −0.07 ± 0.03 dex, and fixed vt=1.39 km / s, vmac = 2.08 km / s.(a) and (b) the macro-turbulence velocity is fixed according to the relation for giants from Hekker & Meléndez (2007) and the microturbulence according to Adibekyan et al. (2015).
