PV diagrams along the molecular outflows of cores #9 (a), #49 (b), #2 (c), #39 (d), #44 (e), and #67 (f). Same convention of position offsets, segments, and lines as in Fig. 5. Contours are 5, 10, 22 to 67 by steps of 15 in (a), 4, 8, 15 to 65 by steps of 10 in (b) and (d–f), 5, 10, 22 to 122 by steps of 25 in (c), in units of σ_CO =2.5 mJy beam⁻¹. Additional 2σ_CO contours aredrawn in dotted line in (b) and (f) to highlight weaker emission. PV areas confused by another outflow in (a) and hot core lines in (c) are hatched.
