APEX CO(3–2) (345 GHz) spectra in a grid of 25 positions (6′′ spacing) in a region of MM2 centered on IRS 9A (source S9 ). North is up and east to the left, and coordinates are in arcseconds relative to Sa . The individual spectra, each covering 60 km s^-1, are displayed over the SABOCA map, with the center and base of each line aligned with the corresponding pointing position. The maximum line peak is 28 K main beam temperature. The beam FWHM is 20′′.
