Hello sundialists around the world!
Who can help me? I am looking for the algebraic relation between the Equation
of time and the eccentricity of the earth orbital. It will help me for
calculating this eccentricity with my own sun dial.
Chris Lusby Tailor gave me a nice hint with the Ptolemaios model, which was
rather effective ( I found e= 0,0172 instead of 0,0167) , but I think that
there must be also some algebraic solution to the problem. Who is aware of such
a solution?
