Orbital flip fraction as a function of inclinations and hierarchy (i.e. outer and inner semimajor axis ratios). The flip fraction is calculated for each combination of the inclination and semimajor axis ratio aper/a by performing 20 integrations with a range of Ω values between 0 and 2π in steps of 0.1π. All integrations have the initial parameters ω = 0, eper = 0.2, e = 0.2 and mper/m = 1. The results for integrations using the DA equations are shown in the left-hand panel and those using the CDA equations in the right-hand panel. The fraction (among the 20 runs) is illustrated by using different colour – blue = 0, magenta = (0,0.25], cyan = (0.25,0.5], green = (0.5,0.75], yellow = (0.75,1), red = 1.
