Resulting synthetic interferometric map of NGC 6302 in the ¹²CO J = 2 − 1 transition. The size of each frame is 20 × 20 arcsec². The LSR velocity is indicated in the upper left corner of each frame. The size and orientation of the synthetic beam, and the contour levels have been adapted for approximate visual comparison with the observations displayed in Fig. 1 in Dinh-V-Trung et al. (2008); emission is represented in a logarithmic scale, with the following maxima (10th contour) depending on the label: 2.4 Jy beam^-1 for “c1” channels, 6.4 Jy beam^-1 for “c2” channels, and 11 Jy beam^-1 for “c3” channels.
