Notes.
λ0 represents the central laboratory wavelength of the spectral line. σ and α represent the cross section (in units of Bohr’s radius squared, a02) and velocity parameter of the atom undergoing the transition, respectively, for collisions with neutral atoms under the ABO theory (Anstee & O’Mara 1995; Barklem & O’Mara 1997; Barklem et al. 1998).
Values taken from Nave et al. (1994).
Values taken from Borrero et al. (2003).
Values taken from Bloomfield et al. (2007a).
Values taken from Bard et al. (1991).
