ALMA ¹²CO J = 3−2 emission map of NGC 6302, binned to 1 km s^-1. The field of view is 11′′ × 20′′. V_LSR velocities in km s^-1 are indicated in each channel. The intensity scale of the contours is logarithmic with the first contour at 40 mJy beam^-1, and a step of 3 dB (i.e. a factor of 10^0.3 ≃ 2) between adjacent contours. The deepest negative contour has a level of −100 mJy beam^-1. Contamination by NS emission (see Appendix A) is highlighted in green wherever it can be spatially resolved from ¹²CO emission. An HST F673N image of the central region of NGC 6302 is shown in the background for comparison purposes.
