Radial distribution of apparent specific angular momentum |j_app| = |v|× r along the equatorial axis of the CALYPSO sources, considering all the velocity gradients observed at all envelope scales, including the reversed gradients and the shifted ones at scales of r ≳ 1600 au (see Fig. 19 and Sect. 5.4) which were excluded in the construction of the PV_rot diagrams in Fig. 16, and in panel b of Fig. 17 for our analysis of rotational motions. The empty circles show the negative apparent specific angular momentum from the reversed gradients along the equatorial axis in the outer scales (r > 1600 au) of the L1448-2A, IRAS2A, IRAM04191, L1527, L1157 and GF9-2 envelopes (see Sect. 5.4.1). The gray curve shows the median profile |j_app | and the solid black line shows the best fit with a broken power-law model.
