Global measurement of the radiative efficiency of the 3D RAMSES run as a function of time (where t = 0 corresponds to the epoch of protostellar birth), performed at R_s = 1.2 au (see Eq. D.1). Top panel displays the outgoing radiative luminosity (solid line) and accretion luminosity (dash-dotted line). Bottom panel presents the time integrated luminosities, yielding the radiative energy (solid line) and the accretion energy (dash-dotted line). Bottom panel also shows the global ^globalf_acc(t) (red line) and local (red circles) radiative efficiency.
