Main beam-averaged 12CO(2–1) line brightness temperature observed in IRC +10 216 with the IRAM 30-m telescope (HPBW 11′′) at the star velocity (V = −26.5 km s-1, Δv = 2 km s-1; see Cernicharo et al. (2015). Dotted contours range from 1 to 50 K. On this, as on the other velocity-channel maps, the brightness scale is linear.
