Continuum-subtracted emission-line maps. Respective maps of [Fe II], H₂ S(7), and selected H i transitions for two representative sources: HV Tau C (top row) and RW Aur B (bottom row) are shown. The green circle marks the 2×PSF FWHM extraction region used for spectral analysis. The red star indicates the 14 µm continuum peak position. Despite the presence of extended outflows in [Fe II], the H i lines are spatially unresolved within the 2×PSF region. Minor spatial shifts between cubes are due to residual pointing jitter (0.2^′–0.3^′) across spectral channels.
