Numerical error of total energy and angular momentum

Relative numerical error of total angular momentum dA/A_0 and total energy dE/E_0 in our numerical integrations N_+/-1,2,3 (upper panel) and F_+/- (lower panel). dE, dA is the absolute change of the total energy and total angular momentum, and E_0, A_0 is their initial values, respectively. Horizontal unit is Gyr.
