Notes. (a) Values taken from Motte et al. (2018a). (b) Velocity at rest estimated with the 13CS(5–4) line, except for cores #1, #2, and #4, for which the O13CS(18–17) line was used instead. A star marker indicates the velocity of the neighboring core that is used for cores detected neither in 13CS(5–4) nor in O13CS(18–17). (c) Maximum velocity offset and length, uncertain by 2 km s−1 and 0.2′′ (0.005 pc), respectively. A star marker indicates lower limits used in our calculations when measurements are confused by line absorption features or neighboring outflows. (d)Position angle of the molecular jet, measured from West to North. A star marker indicates molecular jets that are offset by more than 0.2′′ from their core center. (e)Visual extinction measured over the complete extent of the outflow lobe, uncertain by 30%. A second measure at the tip of the molecular jet is given in parenthesis for lobes covered by more than 3 pixels in the 7 m array continuum map (i.e., with Lmax ≥ 9.6 × 10−2 pc) and when it differs by more than 20%. (f)Less reliable outflow lobes are pinpointed by mentioning their confused environments (denoted with “Conf”) or their nondetection in SiO(5–4) but in CO(2–1) (denoted with “CO”). “(R)” means that the note applies to the red lobe only.
