Maps of the configuration space for a spinning rubble-pile aggregate using different indicators. Each row shows the evolution of a given map in time. The solid red line indicates the breakup limit derived from the granular N-body simulations (ground-truth reference), and the dashed red line indicates the theoretical equilibrium curve described by Eq. (3). The solid green line indicates level lines with FTLE(I_p) = 0 (first row) and DD(I_p) = 0 (second row).
