$\begin{figure} \par\includegraphics[width=7.7cm,clip]{6711fig1.eps}\end{figure}$ Figure 1: Intensity map of the ¹²CO(2-1) line emission at 0.4'' $\times$ 0.3'' resolution (color and contours). The black cross marks the position of the dynamical center as derived in Paper I. The beam size and the linear scale are shown for reference in the bottom right corner. The contours start at 0.6 $\rm Jy~beam^{-1}~km~s^{-1}$ with the same step size. The red dashed ellipse indicates the location of the assumed bar (see Paper I).

$\begin{figure} \par\includegraphics[width=7.7cm,clip]{6711fig2.eps}\end{figure}$ Figure 2: Comparison of the intensity map of the HCN(1-0) line emission (color) and the neighboring continuum emission (contours) at 1.0'' $\times$ 0.7'' resolution. The contours start at 3 $\sigma$ and are in steps of 1 $\sigma$ = 0.21 mJy beam^-1. The black cross marks the position of the dynamical center as derived in Paper I. The beam size is shown in the bottom right corner.

$\begin{figure} \par\includegraphics[width=7.5cm,clip]{6711fig3.eps}\end{figure}$ Figure 3: Gas kinematics in the central 3 $^{\prime \prime }$ of NGC 6946. Middle panel: integrated flux of the negative (positive) velocity component from a double Gaussian fit (see text; white (black) contours) overlaid on the total integrated ¹²CO(2-1) flux (color). Top/bottom panels: typical ¹²CO(2-1) spectra (from single pixels) and their corresponding Gaussian fits display a double-peaked profile throughout the nuclear region; the profile close to the dynamic center shows a third component close to the systemic velocity. The velocity is given relative to the systemic velocity and the y-axis is line intensity in Jy beam^-1 (with a temperature conversion of 200 $\rm K~Jy^{-1}$ ).

$\begin{figure} \par\includegraphics[width=6.3cm,clip]{6711fig4.eps}\end{figure}$ Figure 4: Top: HCN(1-0) intensity map (contours) overlaid on the ¹²CO(2-1) one (color). The HCN contours start at 50% of the maximum in steps of 10%. Both beams are shown in the bottom right corner with the HCN one being the larger one. Bottom: HST $\rm Pa\alpha$ line emission (contours) overlaid on the VLA 6 cm radio continuum (color). The position of the dynamical center (cross) and the 3 mm continuum peak (star) are indicated. The 6 cm beam is shown in the bottom right corner.
