and n(Η₂) maps at the CH₃OH peak (data from Punanova et al. 2018). The blue contour levels correspond to values of 2.0 × 10¹³, 2.5 ×10¹³, and 3.2 × 10¹³cm⁻². The gray contours show the Ν(H₂) contours of 1.0 ×10²², 1.2 ×10²², 1.6 ×10²², 2.0 × 10²², and 2.5 × 10²² cm⁻² from the spectral energy distribution fitting of Herschel data (Spezzano et al. 2016). The dust peak, the CH₃OH peak, and the HNCO peak are indicated as a green diamond, a three-branched triangle, and an upward pointing triangle, respectively.
