APEX beams and the observed spectra superposed on the RN A H₂ 2.12 μm image. The circle sizes correspond to the APEX FWHM at 230 GHz (27′′) and 345 GHz (18′′). The tickline in the spectra is at v_LSR = 3km s^-1. The (3–2) and (2–1) are black and red, and (3–2) and (2–1) lines are green and blue, respectively. The scale in the spectra is . The circle with a thick line corresponds with the Shell A position of G13 and the star displays the OFF position.
