12CO J—3 → 2 red and blue high-velocity gas moment 0 maps tracing outflowing gas are shown as contours. This is overlaid on a 12CO J—3 → 2 moment 0 map that includes gas at all velocities. The velocities used to make the contours are highlighted in yellow in Figure 1. The eastern nucleus has 1.5, 2.25, 3.0, and 3.75 Jy/beam km s−1 contours and the western nucleus has 1.0, 1.75, 2.5, 3.25 Jy/beam km s−1 contours for the blue outflow and has 6.0, 9.0, 12.0, and 15.0 Jy/beam km s−1 contours for the red outflow. Crosses indicate the center of continuum emission in each nucleus.
