    Now I understand your procedure even less:-)
    How exactly you rounded.
    That's why I asked you for the row data.
    
    As a mathematician, I am very surprized how can one extract something
    with 0.1 accuracy from the data which are 10-20 times less accurate,
    no matter how manhy observations you make.
    
    If you don't want to type all numbers type few of them.
    For example:
    time1 sextantreading1, time2 sextantreading2, and so on.
    I mean "as you recorded them". Plus DR coordinates and IC and
    whatever corrections you applied.
    
    Alex.
