¹²CO(2−1) channel maps of CB 26, obtained with PdBI in 2005 and 2009, rotated counterclockwise by 32°. Contour levels start at 15 mJy/beam (2σ r.m.s., see Table 1). Red contours mark the 1.2mm dust continuum emission from the disk (3 and 15 mJy/beam. The reference position is α₂₀₀₀ = 04^h59^m50.74^s, δ₂₀₀₀ = 52°04′43.80″. The ¹²CO synthesized beam size is indicated as the gray ellipse in the lower right corner of the first channel map. The channel number and mean Δυ = υ_LSR _ 5.95 (in km s⁻¹) are indicated in the top left and right corners of the maps, respectively. Maps in the central velocity channels between Δυ ≈ ±1.2 km s⁻¹ are corrupted by resolved-out emission and self-absorption from the extended envelope.
