CO J=1
0 map of the Seyfert 1 galaxy,
NGC 7469 at 2.5
spatial resolution with the IRAM millimeter
interferometer. The high signal-to-noise ratio of these data and the
spectral resolution of 10 km s
have allowed us to glean
kinematic details on spatial scales smaller than this (see
Figure). From model fits we find that the molecular gas comes from a
combination of a 1.5
radius circumnuclear ring and a central gas
concentration associated with the narrow line region (NLR). This
structure is very similar to the molecular structure seen in the Seyfert 2
galaxy NGC 1068, and is consistent with current unified schemes for
Seyfert galaxies. The velocity distribution has a slowly rising (not
solid-body) rotation curve. The gas lies in a plane with a low inclination
angle of 
25
. These kinematic parameters imply a dynamical
mass of 
2.0
10
M
in the central 5
(1.6 kpc), with the molecular mass dominating the dynamical mass.
The dynamical measurements thus allow a calibration of the H
--to--CO
conversion factor in a Seyfert galaxy. We find that the
NGC 7469 conversion factor is 
1.5 times the Galactic value.
