2) Robert and I are just about to go public with something like that and I am ready for the flogging. I am actually looking forward to it. It's got some real stunners.
4) I was up against something like that when I submitted the Pyramid Code Paper to ARCE. The reviewer didn't like the corner approach, but I supplied proof that corners mattered in early dynastic temples in Egypt. I think one needs another piece of evidence to settle it. In that case the PT helped. In this case I am sure you'll find something on the the site which no one has noticed before which will help sway this. I am always amazed what in-your-face-features have gotten over-looked by generations of researchers.
Re Ekur vs Baalbek: The Anti-Lebanon mountains delay visibility, and thus horizontally shift, the appearance of the sun and the helically rising stars. Not so in the plane of Nippur. That might explain how two temples could be looking at the same thing but from different directions. What I need is a good aerial photo of the long axis of Enlil's temple and a heading. Then I will have to recreate the 3500 BC sky and see when what shows up. If that era matches Baal-bek's experience you might just get a hot lead out of this no one has picked up on so far.
