i SPS propellant trapped outside tanks should be subtracted from the total
SPS propellant load for a particular mission to arrive at the tanked
SPS propellant. This tanked amount is then used in the preceeding
tables to arrive at the appropriate SPS propellant Mass Properties.
2 The total SPS propellant load for a particular mission less trapped
in tanks and outside tanks equals nominal deliverable SPS propellant.
