CO emission has been mapped in the Seyfert galaxy NGC 1068 at 22'' spacing with the 14 m FCRAO telescope (HPBW = 50''). Emission is detected at all points out to R = 10 kpc. To derive the cloud distribution on a scale much smaller than the antenna resolution (4.8 kpc), we have implemented an iterative rectification scheme that locates emission within the beam by exploiting the spatial information implicit in the line profiles when the gas kinematics are known a priori (e.g., from optical line studies). This scheme is tested successfully on model galaxies with a small central peak and a ring at intermediate radius.
