Figure 2. a) Diurnal stress at apocenter for Astypalaea Linea. b) Diurnal stress at 1/4 orbit after apocenter. Tension is represented by white lines, compression black. Parts a) and b) can also represent stresses at pericenter and 1/4 orbit after pericenter, respectively, by reversing the signs (i.e. tension black and compression white).
