When this parameter is defined to a non-zero value e, all the planets defined in the file [PlanetConfig->44] are initialized on eccentric orbits of eccentricity e. Note that they all are initialized with x>0, y=0, v_x=0, and v_y>0, and such that they are at apocenter at t=0. If you do not want this, then you need to edit manually the planet[i].dat files, put them in the output directory (see [OutputDir->43]), and perform a [restart->12] run.
