    That conjecture merely explains the two lunars on Nov. 26, 1800. I think
    it's pretty reasonable to say that for those two, his sights were
    acceptable but his work up was sloppy. Also, it speaks to the point Frank
    Reed was making in the "no lunars era" thread. Since Thompson already knew
    where he was, he didn't notice his mistake since the errors mostly
    cancelled each other (by shear coincidence) and gave him answers that he
    expected. Lunars are more of a check on the DR rather than the other way
    around.
    
    Once I get the old almanac pages for the others, then we should be able to
    see whether Thompson was sloppy, error-prone in his work-ups, or doing as
    well as could be expected given the inherent error in lunar theory. Those
    lunars will be better for this since we know exactly where he was and no
    assumptions about his account and his location will have to be made. I'll
    post those findings once I get them.
