Notes. lmax is the maximum level of grid used, lmax = 14 corresponds to about 1 AU of resolution, lmax = 13–2 AU, and lmax = 15–0.5 AU. The quantity nthres is the density at which the sink particles are introduced, while nacc is the density above which the gas is being accreted in the sink, Rsink is the sink radius, Cacc is the fraction of the gas mass above this density threshold and inside the sink radii which is accreted in a time step. The parameter Rest indicates whether the run uses an output of run R2 as starting point or is performedfrom t = 0.
