This useful thread, together with Frank’s recent “Latitude and longitude around noon” problem, have stimulated me to
increase my understanding of this effect. I set out in the attached PDF various
snippets that I have gleaned. They will bore the cognoscenti but may be of
interest to those who share my curiosity. Please note that the tabular
information therein is solely to illustrate the magnitude of the effects under
study and should not be used as a source of data.
