Extinction Correction and the [Fe II] 1.26 μm/1.64 μm Intensity Ratio.

RUBINSTEIN A.E.

Abstract (from CDS):

From imaging observations of [Fe II] emission in Herbig-Haro objects, I find a lower limit to the zero-extinction [Fe II] 1.26 μm/1.64 μm intensity ratio of 2.6 and argue that this lower limit must be close to the true zero-extinction intensity ratio. My extinction determinations using this zero-extinction value yields results on well-studied HH objects consistent with results from other ionic-line spectra, whereas using nearly all theoretical values of [Fe II] 1.26 μm/1.64 μm in the literature gives rise to unphysical results.
