1 mm continuum image of the NGC 6334I region with the velocity integrated intensity map of the ¹³CH₃CN transitionat 303.610 GHz overlaid in grey contours (levels are [3, 20, 40, 60, 100, 150, 180]σ with σ = 0.07 Jy beam⁻¹ km s⁻¹). Pixels with values less than 1% of the peak intensity have been masked out. The locations at which spectra have been extracted are marked for each region. The synthesised beam (~1300 × 962 au) is shown in the bottom left corner.
