Fig. 4

Derived CH₃OH column density map and hydrogen volume density from RADEX modeling. The contours (in gray) are NH₂ levels, the same as those in Fig. 1. The markers in blue represent the dust peak (diamond), molecular emission peaks of CH₃OH (three-branched triangle), HNCO (upward pointing triangle), and c-C₃H₂ (plus sign).
