Time Adjustments

To maintain overall balance amongst the partnership, the values shown above for both Gemini North and South have been adjusted from the nominal partner shares as a result of actual time charged through 2006B. Time trades between partners are also included. The time allocations shown here were approved at the Operations Working Group meeting in January 2007. The number of nights is approximated by int(hours/10).
