Notes. The first column provides the label used for each spectral region (which might include more than one spectral line). Regarding the symbols: Δλ is the pixel size in m Å; n_λ is the number of wavelengths used for that spectral line; λ₀ is the central wavelength for the electronic transition associated with the spectral line; e_low and e_upp are the electronic configurations of the lower and upper energy level, respectively; and E_low is the excitation potential (in eV) of the lower energy level. These atomic data are adopted from Nave et al. (1994). The α and are the velocity exponent and collision cross-section parameters (in units of Bohr’s radius, a₀), respectively, as defined in the Anstee, Barklem, and O’Mara collision theory for the broadening of metallic lines by neutral hydrogen collisions (Anstee & O’Mara 1995; Barklem & O’Mara 1997; Barklem et al. 1998).
