Top: SDSS r-band image of NGC 3447/3447A (left) and the velocity field of Hα emission (right). Bottom: the Hα, monochromatic emission map (left) and its velocity dispersion map (right). All panels correspond to the same field, and are on the same spatial scale with North on the top and East to the left. Black solid lines in the top right panel show the position angles along which the velocity profiles, shown in Fig. 4, are derived.
