<HTML>Hi Stephen,
Seems I'm wasting my time with you. You again misunderstand the problem of precision. With Orion's belt apparent size and tilt angle, the sighting precision achieved by the AE and its tranferral on the ground at Giza is remarkable. You are confusing the precision achieved for base alignment, which involves a length of 230 meters aligned to a point at infinity, with the precision achieved in correlating something like Orion's belt which has an apparent size of 3 cm. converted by blowing the scale by 1:3000 on the ground. If you know anything about engineering scaling and setting out (which I pretty sure you don't), you will realise that what they've achieve is pretty good, considering the limitations and constraints involved.
I really have better things to do than to constantly repeat these points.
Adios.
