Integrated intensity maps (in color scale) of CH₃OH-E 2_−1,2−1_−1,1, c-C₃H₂ З_2,2−3_1,3, and HNCO 4_0,4−3_0,з (from left to right) observed by the IRAM 30 m telescope, showing the different locations of the molecular peaks (Table 2, Spezzano et al. 2017). The contour levels (in orange) show 3.2 × 10²¹, 4.3 × 10²¹, 5.9 × 10²¹, 8.1 × 10²¹, 1.1 × 10²², 1.5 × 10²², and 2.1 × 10²² cm⁻² of the molecular hydrogen column density () map (Spezzano et al. 2016). The markers in blue represent the dust peak (diamond), molecular emission peaks of CH₃OH (three-branched triangle), HNCO (upward pointing triangle), and c-C₃Η₂ (plus sign).
