Top: Reynolds α calculated atvarious bin sizes in r. The function fluctuates strongly at small bin sizes and becomes smooth for bin sizes ≥ 4d x. Bottom: gravitational α calculated atvarious bin sizes in r. The function fluctuates strongly between positive and negative values regardless of the increased bin size. It is impossible to measure the gravitational α in the simulations in this study, probably because of Cartesian discretization. The resolution dx = 0.12 AU.
