db: Since there is no such a thing as "The Lehner Line" the diagram is not worth the bandwidth it is taking however you can still save face by showing us how you arrive at this rectangle and from what alleged line the angles of 48 and 42 and 53 are derived. . You are unable to show it on the large diagram because there is no rhyme or reason to it. It is a bust AND CAN NOT AND WILL NOT WORK..
C. Wayne Taylor who was obsessive about accuracy drew his diagrams plotted from many, many key points taken from Petries triangulation. It is perhaps as accurate a rendition as one is to find. He shows not only that The Lehner Line doesn't exist but proves Clive Ross' lines DO WORK.
