Results of the LTE analysis for cut A, B, and C (from top to bottom). The left panel shows the optical depth τ₁₈ , the middle panel the excitation temperature T_ex , and the right panel the H₂column density. All maps were convolved with a Gaussian of two pixels that corresponds approximatively to the beam size. Pixels within each cut for which the ¹³CO(2–1)and the C¹⁸O(2–1)spectrum had a S/N< 4 are left blank.
