    It could be that I used only the map, rather than observations
    in the case of the first voyage.
    I have to check my records.
    All this was done about a year ago, so I do not
    remember. In some cases only the map was used,
    in other cases, observations.
    
    By the way, I think that their land/shore surveying technique had greater
    accuracy
    than their lunars, so it is more or less irrelevasnt which point
    on the map I compare with terraserver.
    This is confirmed in most (but not all) cases.
    In the cases when this is not so, it is probably because
    the shoreline changed since then.
    
    Alex.
