All Tables

Table 1: We list the position angle (PA), inclination (i), distance (D), spatial scale, coordinates of the dynamical center derived from CO and/or from the locus of the radio continuum source [(RA₂₀₀₀, Dec₂₀₀₀); accurate to $\sim$ 0.5 $^{\prime \prime }$ on average] and systemic velocity( $v_{\rm sys}^{\rm LSR}$ ) derived from CO for NGC 4321, NGC 4826, NGC 4579 and NGC 6951 used in this paper. The spatial resolutions of the CO observations are listed in Cols. 9, 10.
Table 2: We compare the characteristic time-scales of gravity torques ( $T_{\rm grav}$ ), dynamical friction ( $T_{\rm df}$ ) and viscosity ( $T_{\rm visc}$ ) in the nuclear disks of NGC 4321 , NGC 4826, NGC 4579 and NGC 6951. Time-scales are given in units of rotation periods ( $T_{\rm rot}$ ).
