CO line profiles, showing a two-component structure. Left: 12CO(2–1). Right: 13CO(2–1). A-configuration and D-configuration are merged, OTF data are added, and the spectral resolution is 0.5 km s−1. The CO emission is integrated over the central 22′′ × 22′′, i.e., over thefull field of view of the NOEMA antennas at 230 GHz.
