An Update on the Sproul Data
Back in January 2011 Eric Jensen of Swarthmore College, home of the Sproul Observatory, provided me with three stacks of papers from the late Dr. Peter Van de Kamp. These pages contained raw and processed astrometric data on epsilon Aur which. As you might recall, my initial post on this topic explained that there is a strong disagreement between the orbits implied by the Van de Kamp orbital solution and the more recent interferometric data from CHARA.
