Position angles of the COM emission elongation (black crosses) with respect to the mean position angle of the outflow lobes (bicolor cross) for the sources listed in Table 3. Only the transitions with an error on the position angle smaller than 10° were selected. The unidentified transitions were not used and the following molecules with less than five atoms were ignored: CO,13CO, C18 O, SO, SO2, H2CO, H2 13 CO, D2CO, OCS, O13CS, SiO, DCN, C13S, and HNCO. L1448-2A, SerpM-SMM4b, and L1157 have no transitions fulfilling the selection criteria. For each source, the olive circle and the two green squares indicate the angles ΔPAmean and ± |ΔPA |mean with ΔPAmean and |ΔPA|mean the mean deviation and mean absolute deviation, respectively, of the COM position angles with respect to the mean position angle of the outflow. The dispersion around the mean deviation is also displayed. The vertical dashed lines mark a deviation of ±20° from the mean position angle of the outflow. Only IRAS2A1 and SerpS-MM18a fall within these limits with a small dispersion.
