HOPS 169 outflow traced by 13CO (left) and C18O (right) centered at α (J2000) = 5h36m36.ˢ1, δ(J2000) = 06°38′54.″2). Left: 13CO J = 2−1 integrated intensity maps are used to trace the blueshifted (blue) and redshifted (red) outflow lobes. Right: same outflow but traced by the C18O J = 2−1 emission. In both plots, the C18O J = 2−1 integrated intensity map (integrated over velocities close to the system velocity) traces the dense envelope, and it is shown in green.
