Yup. Got the co-ordinates. I had read Burl's Great Stone Circles book, just can't remember which chapter at the moment, but he had some criticisms of proposals of alignments - too many types of monuments included, so many metres off the line and so on. Your piece, this morning, reminded me of it.

I'll have a fiddle with the figures when I get the chance and I might ask for assistance again if I get in trouble, if that's ok?
