From top to bottom: evolution with time of the number of sink particles, of the SFE, and of the total flux emission at 278 GHz (within a total area of 80 000 AU × 80 000 AU) for the two models after the creation of the first sink. The circles indicate the time at which the simulations are post-processed. In the bottom panel, the different lines correspond to the different projection planes as illustrated in the bottom right corner.
