Thus a specific coordinate program (equinox and equator/ecliptic of a specific day, for example J2000.0) could be utilized permanently, but a set of osculating factors for a certain epoch may possibly only be (about) legitimate to get a somewhat constrained time, simply because osculating elements such as All those exampled higher than will not sho
