The Array A-2 weight is based on actual measured weight data. The Flight 5 weight is based on approximately 75% actual weight data with the remainder estimated. The Array E weight is 100% estimated based on the preceding ALSEP systems. Since there are presently two possible experiment combinations which could be included in Array E, the prime and alternate system weights are reported.
