CO emission from IRAS 16342−3814. The colourscale corresponds to the moment-8 (maximum value of the spectrum for each pixel) image of the CO(J = 3 → 2) emission. The contours indicate the CO(J = 1 → 0) emission averaged over the velocity range −10 < v_offset(km s⁻¹) < +10 with values (0.007, 0.01, 0.02, 0.03, 0.05, 0.1, 0.2, 0.3) Jy beam⁻¹, where the first contour represents four times the value of the rms. The orange dashed line delineates the region that contains emission from the EHVO. The ellipses located at the lower left corner indicate the synthesised beams of the CO(J = 3 → 2) and CO(J = 1 → 0) observations, respectively. The beam size of the CO(J = 3 → 2) observations is the same as in Fig. 2 and the beam size of the CO(J = 1 → 0) observationsis 1.′′25 × 1.′′18 with PA = −58°.
