Notes. The listed knots can be identified in Fig. 2.(a)Following the notation used inBeltrán et al. (2009).(b)Spectra spanning the indicated band. (c)AV from 1.644/1.257 μm [Fe ii] line ratios. (d)Fits in this band underestimate Tex and overestimate AV (see text). (e)H2 1–0 S(3) line point at 1.957 μm not included in the fit to obtain a consistent result.
