>> I'd be interested in hearing of any pre-1620 eclipse observations in
which locations are _solidly_known_, and how they compare when using both
Guide's default dT and mine as given above. <<

There are a whole host of ancient eclipse records / maps / formulae
for delta-T in Historical Eclipses and Earth's Rotation by Stephenson.
What is your particular interest in ancient eclipses ?

Richard.
