This parameter has to be used together with the `ReleaseDate` parameter. They both are relative to planet 0 only, and they can be used to specify a forced migration (with constant, arbitrary ). The planet 0 trajectory is forced for `ReleaseDate`, and is such that at `ReleaseDate`, the planet semi-major axis is equal `ReleaseRadius`. At , the planet semi-major axis is the one indicated in the planet configuration file (see `PlanetConfig`). Between and `ReleaseDate`, the semi-major axis of planet 0 is an affine function of time. Its angular speed is the Keplerian one corresponding to its instantaneous semi-major axis.
