[FeII]λ1.644 μm velocity and dispersion field derived from single-Gaussian fits. The black box indicates our FoV. North is up and east to the left. Gray contours represent [FeII] flux isophotes to guide the eye. Top: [FeII]λ1.644 μm velocity field, 21 cm radio contours in red (.5, 1, 2 and 4 mJy beam^-1 with a beam size about four times smaller than our angular sampling) taken from Mundell et al. (2003), and [FeII]λ1.644 μm contours in gray. Numbers in the plot indicate velocities of prominent [OIII] clouds (taken from Kaiser et al. 2000). Bottom: [FeII]λ1.644 μm dispersion field, 21 cm radio contours in red (.5, 1, 2 and 4 mJy beam^-1 with a beam size app. four times smaller than our angular sampling) taken from Mundell et al. (2003), and [FeII]λ1.644 μm contours in gray. Numbers in the plot indicate dispersions of prominent [OIII] clouds (taken from Kaiser et al. 2000).
