(meteorobs) AMS Meteor form

If  I may add to what Felix and others have already noted, the accuracy 
notation would also have to do with confidence in the actual placement of 
the plot line on the map -- how sure is the observer that he/she has plotted 
the meteor correctly.

This is important, as I have witnessed three *experienced* observers plot 
the same meteor (myself being one of the three)-- a bright -2 with a long 
path length -- differently.  Not *too* differently, but  with such a long 
path length, more error will creep in, and establishing a radiant would be 
quite difficult.

Just my 02/100 of a dollar...
