Not an answer, but rather a question. It strikes me the time of the solstice to the second is the critical unknown in solving for the location(s). Recalling Herbert Prinz's March 2006 explanation of how the equinox time to the second is determined relative to the two fundamental references, how is determining the exact time of solstice rigorously defined? http://fer3.com/arc/m2.aspx/Welcome-Spring-or-Fall-HerbertPrinz-mar-2006-w27802
