Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles ( P.A.= 5 ^ { \circ } , 50 ^ { \circ } , 95 ^ { \circ } , 125 ^ { \circ } , and 155 ^ { \circ } ) of the nearby barred spiral NGC 6221 .
The observed kinematics extends out to about 80 ^ { \prime \prime } from the nucleus .
Narrow and broad-band imaging is also presented .
The radial profiles of the fluxes ratio [ N { \scriptsize II } ] ( \lambda 6583.4 Å ) /H \alpha reveal the presence of a ring-like structure of ionized gas , with a radius of about 9 ^ { \prime \prime } and a deprojected circular velocity of about 280 km s ^ { -1 } .
The analysis of the dynamics of the bar indicates this ring is related to the presence of an inner Lindblad resonance ( ILR ) at 1.3 kpc .
NGC 6221 is found to exhibit intermediate properties between those of the early-type barred galaxies : the presence of a gaseous ring at an ILR , the bar edge located between the ILR ’ s and the corotation radius beyond the steep rising portion of the rotation curve , the dust-lane pattern , and those of the late-type galaxies : an almost exponential surface brightness profile , the presence of H \alpha regions along all the bar , the spiral-arm pattern .
It is consistent with scenarios of bar-induced evolution from later to earlier-type galaxies Tables 3 , 4 , 5 , 6 , 7 and 8 are only available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr ( 130.79.128.5 ) or via http : //cdsweb.u-strasbg.fr/Abstract.html .
