Scientific paper

The 12.8-micron fine-structure line of Ne II has been mapped in the central 25 arcsec of NGC 253 with a 6-arcsec beam and 0.1-0.15-kayser spectral resolution. As in visible studies, both circular and noncircular motions were observed. However, there are major differences between the Ne II velocities and those measured in the optical and radio regions.
