Notes. (a) Outer radius of the C18O emission from the PdBI datasets. (b)Transition radius between C18O and N2H+ determined from column density profiles along the equatorial axis (see Appendix D). Rtrans is defined following criteria (i), (ii), (iii), and (iv) which are detailed in Sect. C.3. (c) Intermediate radius in N2H+ emission between the combined and 30m datasets. (d) Envelope radius from PdBI or 30m dust continuum emission. See Table 1 for the references. (⋆) For IRAS4A and IRAS4B, we used the N2H+ emission from the PdBI datasets instead of the combined datasets to build the PVrot diagram. In these cases, Rint is the maximum radius below which we used the PdBI dataset. (⋆⋆) For L1521F, we only used the C18O emission from the combined and 30m datasets to build the PVrot diagram (see Appendix H). For this case, we used the combined dataset up to Rtrans and we used the 30m dataset up to Rout.
