Parallel tracks on the M − Ω and L − Ω planes for a simulation with α = 10⁻⁷, q = 0.56, D = 0.5, and p = 1.3. Solid black lines are the lines of (Ω_K−Ω)M = const and (Ω_K−Ω)L=const. Time is color-coded (see the colorbar on the right). To demonstrate the parallel tracks effect during multiple observation runs, we show only the data points in 10⁴ s intervals separated by 10⁴ s gaps.
