                         2) Drogue tracking
Notes:                   1) Stations will be occuppied for extended
                         periods. Drogues to be tracked when on station.
                         2) Flow cytometers will dominate the main lab and
                         require 208V, 3ph, 50amp service.

                         underway VPR, is continuously cycled in water
                         column by winch movement.
                         4) A 20' lab van may be substituted for the
                         isotope van.
