CO (J = 2–1) emission associated with the large-scale outflow of CARMA-7 (central red and blue contours; Plunkett et al. 2015). The integration ranges are -20 to 4 km s⁻¹ for the blueshifted component and 12-40 km s⁻¹ for the redshifted component. The nth contour occurs at a level of ($\sqrt{2}$)ⁿ × p times the maximum signal strength, where the maximum signal strengths are 3.5 and 6.3 Jy beam⁻¹ km s⁻¹ and p represents 10% and 9% of the signal strength for the blueshifted and redshifted emissions, respectively. Here, n ranges from 0 onwards, incrementing by integers. The background is an ALMA map of 1 mm continuum emission (Plunkett et al. 2018). APEX has a half-power beam width of 34″ at 181.310 GHz (denoted by an orange circle) and 19.2″ at 325.153 GHz (denoted by a magenta circle). The companion source whose center is also indicated by a green cross in the southeast is CARMA-6.
