Thanks to David Emigh, Leigh Palmer, and David Bowman for taking the time to
share their knowledge of astronomical units with me. Your contributions
were a great help to my understanding. I'm new to PHYS-L@lists.nau.edu
<mailto:PHYS-L@lists.nau.edu> and am very impressed by the expertise of its
members and their willingness to help one another.
