Notes. Column descriptions: Elow: lower level energy. “VdW”: parameter(s) used to calculate line broadening due to van der Waals interaction; negative numbers: logarithm of the line width per perturber at l04 K in rad s-1 cm3 (log γW); positive numbers: integer part: broadening cross-section at a velocity of 104 m s-1 in atomic units, fractional part: velocity parameter (see Barklem et al. 2000). “Source”: reference code for the atomic data (see below), or “S”: log gf and log γW determined from a fit to the solar spectrum (reference code in parentheses: source of the initial data); if two codes: log gf, log γW. “K/M”: line was used in K- or M-dwarf analysis (some only in the P82 or P84 spectra, see Table 1).
