(From Document 618-306, Revision D)
The LECP EDR science record is designed to a 48-second instrument measurement period. Any data not present during the instrument measurement will be filled with binary zeroes.
A logical record corresponds to an instrument measurement period and in this instance is also the science physical record structure.
The science logical/physical record structure is diagrammed in Figure 4.3-1.
