Energies and assignments for the lowest 14 levels of the Ar iii system presented in eV. Stancalie, Pais & Mihailescu (2012) and Munoz Burgos et al. (2009) are theoretical R-matrix results for electron impact excitation calculations, and the NIST results are observational data taken from Saloman (2010). The remaining results are the present works summarized in Table 1.
