    Lunar Distance:"Straight line vs.Line of best Fit"
    From: Mike Burkes

    Hi folks, This is a subject I discussed with George last Summer and it involves the use of solving a set of Lunars such that you pick shots that form a straight line e.g. Frank's Jupiter Lunar shots 1,5, and 7. In this case those shots formed a straight line which paralleled the line of best fit but  the average time of those 3 shots was 04-42-12 as opposed to all seven's average of 04-40-33 but most importantly the GMT Lunar was 04-40-03 which was pretty close to Fred's. In some of my past shots the " straight line" observation results surpassed the line of best fit results! A possible explanation could  have been the overall quality of the observation set. Navigation texts do not refer to this "straight line" method so I will stick to " line of best fit" and not reinvent the wheel! Any comments would be appreciated and thanks! Mike Burkes.
