Notes. ^(a)Number of lines whose wavenumbers matched previously observed wavenumbers within ±0.2 cm⁻¹ for Nd IV, and ±0.05 cm⁻¹ for the other species. ^(b)Using Ritz wavenumbers allowed by ∆J = 0, ±1, but not J = 0 ↔ 0 and parity selection rules for E1 transitions of the energy levels on the NIST ASD (Kramida et al. 2022) that were mostly from Martin et al. (1978); Blaise et al. (1971, 1984). ^(c)147 of the 579 lines belong to the 4f³6p–4f³7s and 4f³6p–4f³6d transitions, which will be reported in a future publication. ^(d)An estimate excluding multiply identified lines, unknown coincidental wavenumber matches, and unfitted lines that are too weak or in unknown blends.
