Moment maps and integrated emission comparison between three simulated and best-fit models. From top to bottom: Model 1, Model 2, and Model 3, whose parameters are listed in Table 2. Left panel: comparison of simulated and best-fit moment maps. From left to right: integrated emission, LOS velocity, and velocity dispersion maps. Right panel: comparison of simulated data (dotted blue) and best-fit integrated profile (red). Residual emission is shown in green.
