Primary beam corrected integrated intensity maps in Jy beam⁻¹km s⁻¹ for the different species detected with the SMA. In each plot contours start at 5σ and continue in intervals of 5σ, except for panel a-c for which contours start at 10σ and continue in intervals of 10σ. Shown are (a) CO J = 2 − 1 (σ= 0.96 Jy beam⁻¹km s⁻¹), (b) ¹³CO J = 2 − 1 (σ= 0.32 Jy beam⁻¹km s⁻¹ ), (b) C¹⁸O J = 2 − 1 (σ= 0.13 Jy beam⁻¹km s⁻¹), (d) H₂CO 3₀₃ − 2₀₂ (σ= 0.23 mJy beam⁻¹km s⁻¹), (e) H₂CO 3₂₁−2₂₀ (σ= 88 mJy beam⁻¹km s⁻¹), (f) H₂CO 3₂₂ − 2₂₁ (σ= 0.14 mJy beam⁻¹km s⁻¹). The circular field-of-view corresponds to the SMA primary beam. The size of the synthesised beam is shown in the lower left corner of each image. The white and orange stars and the orange circle mark the position of the Coronet cluster members as in Fig. 1.
