Integrated intensity maps using two transitions for both isotopologues of CH₃ OH, the main CH₃CN isotopologue, and one transition for each of the ¹³C isotopologue towards IRAS 2A. Respective rest frequencies (in GHz) are shown in the bottom-right corner, the beam (half power beam width, HPBW) on the bottom left. Multiplication factors (e.g. ×3, next to the species name) were applied to some species and transitions to be able to use the same intensity scale for all panels. The yellow dashed contour is at 5σ, where σ is the rms noise level (in K km s⁻¹) and is written in the top-right corner.
