I would like to know whether the equation of time is used when an analemmatic dial is read. I have pictures of human analemmatic dials where the position of the gnomon is indicated by an analemma, and some where the position of the gnomon is indicated by dates on a central straight line. Both cannot be correct! My gut reaction is that the analemma takes care of the equation of time automatically, but would like confirmation of that, and whether the analemmatic dial with dates on the straight line need equation of time correction.
Does one use the equation of time on a shepherd's dial? What happens to the e. of t. in a leap year? Should we have a new e. of t. each year? Thanks for your help. Carpe horam Peter Ransom ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
