Extreme velocities from the bicone surfaces and position velocity diagrams extracted from the models by Das et al. (2005) and Storchi-Bergmann et al. (2010). Row 1: velocities on the bicone surfaces that are nearer and farther to the observer according to the Das et al. (2005) model. Color scales from −700 km s^-1 (blue) to 700 km s^-1 (red), contours are in steps of 100 km s^-1. Major tick marks correspond to 0.5 arcsec. The surfaces shown cover our FoV. North is up, east to the left. Row 2: same as row 1 for the constant-velocity model by Storchi-Bergmann et al. (2010). Row 3: position velocity diagrams extracted from pseudoslits aligned along the NLR at a position angle of 60° according to the Das et al. (2005) model. The slitwidth/slitlength is 0.15/5 arcsec and the pseudoslits are moved −0.2, 0, 0.2, and 0.4 arcsec away from the nucleus perpendicular to the direction of the NLR. The black area indicates the region in the pv-diagram from which emission is expected according to the model. Note that our observations only cover the inner arcsecond. Row 4: Same as row 3, but for the constant-velocity model by Storchi-Bergmann et al. (2010).
