I was about to ask for the specific papers of time calibrations, even if 
the overview presentation indicates that the verification steps I expect 
to be there have been done. Also the path calibrations needs to be 
described more in detail than in the paper.

First thought was that someone forgot to compensate for GPS antenna 
cable delays.

Do you have direct fiber between the locations?
