Left: total intensity of the ¹³CO emission in the area around HBC 722, integrated for the 0–9 km s^-1 velocity range. The grayscale image and the red contours are IRAM PdBI+30 m observations from this work, while the blue contours are SMA data from Dunham et al. (2012). For the ¹³CO(1–0) line, contours are displayed at 4, 8, 12, ...σ, with σ = 0.09 Jy km s^-1, while for the ¹³CO(2–1) line, contours are at 4, 8, 12, ...σ, with σ = 0.3 Jy km s^-1. Right: total intensity of the ¹³CO emission in the area around HBC 722, integrated for the 5.46–6.52 km s^-1 velocity range. Contours are at 4, 8, 12, ...σ, with σ = 0.03 Jy km s^-1.
