Left: adopted X-shooter slit over a [Fe II] 1.64 μm narrow band image of the HH34 jet obtained with LBT-LUCI (Antoniucci et al. 2014a). The blue circle indicates the source position at α = 05^h35^m299 and δ = −06°26′58″. Right: normalized intensity profiles of [O i]  6300 Å, [S ii] 6731 Å, and [Fe ii] 1.64 μm along the HH34 jet. Distance in arcsec is measured with respect to the HH34 IRS source. The spatial regions we adopted for the spectral extraction are indicated by dashed vertical lines.
