Fig. 6.
Top panel: maps of the CO J:2-1 velocity dispersion (left panel) and velocity residuals after subtraction of the ModC2014 rotation model (right panel) for the inner FOV. Contours in both panels show the moment 0 (integrated flux) map of the CO J:2-1 emission, ranging from 0.4 mJy beam−1 km s−1 to 5.4 mJy beam−1 km s−1. Bottom left panel: moment 3 (skewness) map of the CO J:2-1 emission for the larger FOV, shown in color following the color bar: blue colors represent spectra with excess emission towards the blue side of the weighted mean velocity. The CO Moment 0 (total flux) map is overlaid with black contours. Bottom right panel: as in the top right panel but for the larger FOV. Pixels with velocity less than −90 km s−1 in the right panels are shown in white. Contours in bottom panels show the moment 0 (integrated flux) map of the CO J:2-1 emission, ranging from 0.4 mJy beam−1 km s−1 to 8.4 mJy beam−1 km s−1.
