For the barred galaxy NGC 2336, stationary models are constructed which reproduce in a consistent manner the observed NIR surface brightness distribution and the observed HII kinematics in those regions affected by the bar. This procedure can answer the question whether the observed kinematics of the galaxy agree with the model predictions derived from the observed distribution of visible matter (assuming that plausible corrections for the presence of dark matter can be applied). It turns out that the parameter values from the morphological decomposition and those needed to fit the HII rotation curves of NGC 2336 best are in excellent agreement.
