That is very helpful.......... I still have a little difficulty visualizing negative parallax.......I can visualize parallax based on figure1 and Zero would not demonstrate any angle difference but it is negative parallax that is difficult to visualize is it just a measurement of the angle less then the expected mean of zero..in which case the difference in the angle of observation from two sightly different locations actually diverges rather then converges?..The bell curve is very interesting as you point out it is rather symmetrical and structured and makes it difficult to argue that the 46% of the measurements used external of the rest of the measurements is anything other then just an arbitrary dismissmissal of data based on preconceived ideas about the cause of parallax...... As you put it "the number and symmetrical distribution of these values would tend to deny this as being anything other than an exception to the rule."

Your comments and suggestions would be appreciated. Best wishes, Neville. --------------------------------- Inbox full of unwanted email? Get leading protection and 1GB storage with All New Yahoo!
