    Missed pasting the splits!
    
    2000.
    "03-09A","20:01:57.0",13.290,55.13,2
    "03-09A","20:02:27.8",14.703,82.58,2
    "03-09A","20:03:10.3",13.290,55.13,2
    "03-09A","20:03:40.7",00.615,60.32,2
    
    1B was about time predicted, but again I can't make the splits fit.
    "03-09B","20:59:45.9",07.807,26.22,2
    "03-09B","21:00:15.4",06.859,33.37,2
    "03-09B","21:00:40.5",06.000,37.27,2
    are too far right of the Beehive and Pollux on the first two
    "03-09B","20:59:45.9",08.139,24.02,2
    "03-09B","21:00:15.4",07.245,30.60,2
    do not give any bright split (1/15 above) for the third point.
