Approximate achievable change in solar illumination for the case of a single 3:5 resonant orbit (1 orbit sequence) or a combination of 3:5 and 1:1 resonant orbits (2 orbits sequence) as a function of time duration in month. The latter offers different amount of total change depending on how many are flybys performed at each of the two orbits
