Notes. Left: Forbidden [Fe II] lines detected in our observations with the vacuum/rest wavelength (λ), electronic spin states (S₁-S₂) in each respective line transitions (separated by horizontal lines with name of each level’s electronic configuration), the Einstein A-coefficients (A), the lower and upper energy level (E_range), the range of intensity line ratios taken with respect to the 1.644 µm line using peak line intensity (F_line/F_1.644). We use both the Atomic Line List version:3.00b5 updated on 10/02/2023 and NIST Atomic Spectra Database for the Einstein A coefficients and upper energy. Both databases report slightly different values for rest wavelengths, Einstein A-coeffs, and upper energy levels. In many cases, only NIST reports the Einstein A. Values with upper script “1” are from the atomic line list and “2” are from NIST. For the case of the 1.1885 µm line, we note that only the atomic line list reports this line and no Einstein A-coefficient is reported. It is possible this is a different line such as [P II] as discussed in Oliva et al. (2001). Right: H₂ lines detected in our observations with the vacuum/rest wavelength (λ), rotational level (Level) in each respective ro-vibrational transition (separated by horizontal lines with name of the ro-vibrational transition), and the Einstein A-coefficient (A) derived in Turner et al. (1977),the upper energy level (E_upper) taken from Dabrowski (1984), the range of intensity line ratios taken with respect to the 2.122 µm line using peak line intensity (F_line/F_2.122). The properties of each line except for the last column are taken from the Gemini Important H2 lines list.
