Cool to see you guys here - as a UW undergrad I visited the lab once and was amazed by all of the effects you had to take into account to reduce error. Wasn't it something like the experiment can pick up the sun shining on the bricks of the building and shifting it, and the changes in the level of groundwater after it rains? I never understood why you didn't have the apparatus in the middle of the desert.

What sort of error reductions and changes allowed the new distance measurements?
