Coordinates!? a) What sort of coordinate system do you use for mapping the positions of the objects?
--b) Where is the origin of your coord system - Earth? Sun?
--c) Given that everything is moving relative to everything else, aren’t the coordinates of everything out of date the minute you record them in your database?
--d) Do you compile multiple observations and can you get direction & velocity vectors for everything you locate and record?
--e) Do you assume a uniform uncertainty value for each object?
