Notes. Optical values for ionic abundances were used for ions not observable in IR spectra. ICFs applied to account for [Ar II] and [Ar IV] contributions – see Sect. 3.5. Literature values from Henry et al. (2010). Literature abundances in italics are from sources given in Sterling & Dinerstein (2008). * Upper limits for 6.99 μm [Ar II] are inaccurate due to the contribution of the H2 0–0 S(5) lineat 6.9 μm.
