' this case begins with the concentrations in position 5 of ft71f001
' which has 12 positions. position 1 has the end of irradiation
' concentrations from the sas2 case. position 2 has the concentrations
' from the end of the sas2 decay case (zero length). positions
' 3 through 12 are from the origen-s case run separately.
