CH₃OH zeroth-moment map and pv-diagrams for the transitions listed in Table 1. The top row shows the zeroth-moment map calculated over a velocity range of [−55, −30] km s⁻¹; contours start at 30% of the peak and increase by 15%. The white cross marks the position of the continuum peak. The beam is shown in the lower left corner. The symmetry of the methanol molecule is labelled ineach panel, as well as the upper level energy of the transition. The subsequent row shows the pv-diagram along the Δα axis and averaged over the extent of the cube, corresponding to ~2.5′′. The right-ascension offset of the continuum peak and the v_lsr velocity of the source are marked with a white dotted line. Dashed lines show v_lsr ± 4.5 km s⁻¹, corresponding to the peak velocity of the CH₃OH spots.
