Kinematics of the central region of NGC 1316. The regions have sizes of 80″ × 30″. The orientation is the same as in Fig. 3. The nucleus is at p = 138, q = 326. Upper panel: [NII]6583 velocities for the two central fields. Conspicuous is the horizontal feature with kinematical properties that resemble the bulge rotation. Middle panel: map of the difference “stellar velocities minus [NII]”: horizontal feature follows the direction of the bulge’s rotation. This strongly suggests the existence of a dusty gas disc. Lower panel: velocity dispersion of the [NII]6583 line. The mere dispersion values may hide complicated velocity structures changing on very small scales.
