Integrated intensity maps of detected molecular emission lines. In each panel the molecule and transition are noted (see Table A.1). The color map shows the integrated intensity of the line emission. The white contours indicate the 5σ level of the integrated intensity (σ = 1.2 K km s⁻¹). The green contours show the 1.37 mm continuum emission with levels at 5, 10, 20, 40, and 80σ (σ = 0.59 mJy beam⁻¹). The beam size of the spectral line data (0″. 47 × 0″. 36) is shown in the lower left corner. The white bar in the top right corner indicates a spatial scale of 3330 au (1″).
