Notes.

^(a)

Full term designations for the lower levels are 3d⁶(⁵D)4s a^4,6D_J and 3d⁵(⁶S)4s² a⁶S_5/2.

^(b)

Ritz wavenumber.

^(c)

Transition probability, the uncertainty is given in brackets (± ).

^(d)

The uncertainty in the log (gf) is expressed in dex, where ± 0.01 dex corresponds to approximately ± 2.5 per cent.

^(e)

The previous laboratory log (gf)s from Booth et al. (1984), the uncertainties in the log (gf)s of Booth et al. (1984) are those assigned by NIST, Fuhr & Wiese (2003).

^(f)

Semi-empirical log (gf) calculations of Kurucz & Bell (1995).

^(g)

Radiative lifetime values, τ, for are from Schnabel et al. (1995) and for are from Kronfeldt et al. (1985).
