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 2008A. Time trades between partners are also included. The time allocations shown here were recommended by the Operations Working Group in July 2008. The number of nights is approximated by int(hours/10).
