Moment maps of NED01 computed within a box of size 30″ and including pixels above a CO(1–0) intensity threshold of 0.01 Jy beam⁻¹ and within v ∈ [ − 500, 500] km s⁻¹. Left: Intensity (moment 0) map, with contours plotted at [0.1, 0.3, 1, 3, 5, 8] Jy beam⁻¹ km s⁻¹. Centre: Velocity (moment 1) map, with contours plotted every 30 km s⁻¹; the letters indicate the three CO(1–0) components discussed in the main text, where A indicates the main rotating CO(1–0) disk. Right: Velocity dispersion (moment 2) map, with contours plotted at intervals of 30 km s⁻¹.
