Fig. 10
Top panel: for source #1 the zeroth moment map for CH3CN(372−362) integrated from –13 to +10 km s-1. The white contour outlines the 3σ level of 0.51 Jy km s-1. Middle panel: rotational temperature map derived with XCLASS from the full CH3CN(37k−36k) ladder (k = 0...10). Temperatures outside the CH3CN(372−362) 3σ level are blanked. Bottom panel: for comparison, the 438 μm continuum emission converted to Planck brightness temperatures. The black contours show in all panels the 438 μm continuum emission in 4σ steps of 28 mJy beam-1. The beam is shown at the bottom right of each panel.
