Table 1

Atomic parameters for the lines used in this work together with EWs and absolute abundances in the Sun from the Kurucz ATLAS solar spectrum and considering the log g corrected values.

Element	λ (Å)	χ_l (eV)	log gf	EW (m Å)
C I	5052.15	7.68	–5.166	34.5	8.466
C I	5380.32	7.68	–1.616	21.0	8.473

O I	6158.17	10.74	–0.296	3.7	8.722
[O I]	6300.30	0.00	–9.717	3.4	8.635
Ni I	6300.33	4.27	–0.211	2.0	6.250

Notes. Stellar parameters for the Sun are T_eff = 5777 K, log g = 4.40 and [Fe/H] = 0.0 dex (A(Fe) = 7.47 dex). The last column corresponds to the absolute abundances.
