Continuum-subtracted channel maps for [Fe II] 1.644 μm. The 14 panels show that the [Fe II] emission covers a wavelength range from −220 km s−1 to 243 km s−1. The peak position of the continuum flux is indicated by a white star. Contours in units of erg s−1 cm−2 μm−1 consist of nine levels from 2 × 10−15 to 3.2 × 10−13.
