 * Any occulting body can be provided (Earth, Moon, etc.). Multiple occulting bodies can be added using method <code>addOccultingBody</code>. By default, one occulting body is included at construction.
 * Eclipses computation can be deactivated through method <code>setEclipsesComputation</code>. By default eclipses computation are activated.
 Before implementing the solar radiation pressure (that takes into account Earth flattening), one has to define a vehicle with radiative properties. To do so, it is advised to consult the page which describes how to build and use [SPC_VEH_Home the Assembly] ([SPC_VBU_Home see also...]).
