My data files are in J2000 coordinates. As far as operating scope.exe, as
long as the coordinate year is consistent, the errors will be very very
small. For instance, stay with all J2000 coordinates, including the
initializations and the goto/tracking will be extremely accurate.
Eventually this will start to fail, but by then, coordinate year and proper
motion will be added.
