    Appended are all of the 2-line elements from the launch released so far, via
    NASA/GSFC/OIG.
    
    They confirm that the upper stage compensated for the under-performance of the
    CBC stages, to achieve very nearly the intended 27.3 deg, 275 km X 36,394 km
    orbit.
    
    They also confirm the consequent shortfall of its final burn, resulting in a
    final orbit (assuming the elements are reliable) well short of the intended 10
    deg, 36,342 km circular orbit.
    
    Hopefully, only minor fixes will be required.
