Fig. 6
Emission line radial velocity maps for some of the emission lines that clearly show velocity structure. From left to right: Hα, Hβ, [N II]λ6584, and [O III]λ5007. Top row: before correction but after subtraction of the median value. Bottom row: after correction (see text for details). All maps are smoothed with a 2-pixel wide Gaussian and the scale ranges from −50 km s−1 to +50 km s−1.
