Subject: Hall D ramp length update 1410 Tuesday

I now have a clean solution at 106m between point of tangency and radiator, with
final beam height 1.25m below grade. (grade == 33' above mean sea level) 

If you wish to leave a total of 10m at the bottom of the ramp for future (post-GlueX)
flexibility, 113m at that final beam height.  

I have a clean solution with final height 1.5m above grade and the "flexible"
10m at 127m between point of tangency and radiator.  I have not attempted the 120m
solution at this beam height, but wouldn't expect it to take more than an afternoon. 

I will do no more work on the hall D line until I receive guidance on preferred
solution.
