  16. 16. Reasoning Behind Calculation<br /><ul><li>How do measurements of single proper motions yield the proper motion of the nebula as a whole?
  17. 17. Average motion experienced by symmetric pairs.
  18. 18. Average motion experienced by ALL symmetric pairs combined.
  19. 19. Proper motion of the nebula has to subtracted out of individual proper motions in order to get the actual proper motion of the feature.</li></li></ul><li>Why do these measurements?<br /><ul><li>Calculate the age of the nebula and the features in it.
