Same as Fig. A.1, but for ¹³CO(1−0), obtained with OVRO in 2001. Contour levels start at 70 mJy/beam (2 σ r.m.s., see Table 1). Maps in the central velocity channels between ~ ±1.2 km s⁻¹ are corrupted by resolved-out emission and self-absorption from the extended envelope. Maps in the central velocity channels between Δυ ≈ −1.0 and 0.5 km s⁻¹are corrupted by resolved-out emission and self-absorption from the extended envelope.
