ALMA NS emission map of NGC 6302. The field of view is 11′′ × 16′′. 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 25 mJy beam^-1, and a step of 2 dB (i.e. a factor of 10^0.2 = 1.585) between adjacent contours. Severe contamination from ¹²CO J = 3−2 is apparent from V_LSR−34.4 km s^-1 to −24.6 km s^-1, and is highlighted here in green contours. An HST F673N image of the central region of NGC 6302 is shown in the background for comparison purposes.
