Modeling vertical structure in circular velocity of spiral galaxy NGC
  4244
  We study the vertical gradient in azimuthal velocity of spiral galaxy NGC
4244 in a thin disk model. With surface density accounting for the rotation
curve, we model the gradient properties in the approximation of quasi-circular
orbits and find the predictions to be consistent with the gradient properties
inferred from measurements. This consistency may suggest that the mass
distribution in this galaxy is flattened.
