    > Interesting results. BTW, which TT-UT value did you use for your own computations ?
    
    
    67.980  USNO MICA
    67.640  SofaJpl demo program (automatic estimate)
    67.644  Tinyac (correct delta T from IERS Bulletin B)
    ?       JPL HORIZONS
    
    Since the Sun moves about 1° per day, one second error in delta T causes
    about 1° / 86400 = .000012° error in GHA.
