Channel maps showing the 12CO J = 2−1 emission from the half-channel-shifted image cube. The color map starts at 5σ. The synthesized beam is shown in the lower-left corner of each panel. An interactive version of the figure made with TRIVIA is available. Controls at the top allow the user to zoom, pan, and rescale the images. The controls at the bottom include a slider and play/stop buttons to cycle through the channel maps. Placing the cursor in the image will display the positional offset and intensity.
An interactive version of this figure is available in the online journal.
