Paul, > This implies the altitudes were shot 3 or 4 minutes before the mid time > of the lunars. But I wonder, were the observers that dumb? They were not dumb. They knew what they were doing. A degree error in an altitude sight does not affect the lunar reduction. If there was one observer, it was natural to do the whole series of the lunars without interruption, and the altitude sights before or after that. Or one before and one after. After all, they did find their longitude to 5 miles accuracy, which is an excellent result. They were not dumb. Alex.
