EN006 US Debris object not registered with the United Nations. The document swaps inclination and period for two of these objects, the obvious error has been corrected. This is probably a misprint for 562.0. This was a typo for the correct 81.50 deg. It was actually on a lunar impact trajectory.
Orbit given is spurious.
1968-02A registered as category D, but is actually a category B object. Cosmos 221 perigee was given as 22 km, this is a typo for 220 km. This orbit is clearly spurious. Beta Tau 3. EN023 Object, registered by the United States, is a Canadian payload.
