Global appearance of star cluster surrounded by its gas environment, at a spatial scale four times larger than in Fig. 1. The four simulations are visualised at the same time: 3.5 Myr. Each row corresponds to a different simulation. From top to bottom: are the simulations without feedback, with protostellar jets only, with HII regions only, and with both jets and HII regions. The first two columns give column density along the y and x axis of the simulation, and the third column gives the mean of the velocity norm integrated along the line of sight, weighted by the density. The colour scales are not common and depend on each map. The overplotted red circles represent the sink particles.
