    I haven't worked it yet but the apparent retrograde motion in
    observation c and the 1? discrepancy leads me to wonder if they were
    measuring to the wrong side of the moon. Trying to line a star up on
    the shadow line could lead to the large errors that are apparent in
    their data (don't ask me how I know this). As well, if they were on
    the wrong side and they took the wrong sign of the semidiameter, this
    could lead to an error of about a degree. Hmmm...I guess it's a bit
    hard to believe they could make that many errors. I suppose I should
    try working it to see how it works out.
