IMP-8 Intermediate Flex File Format
IMP-8 intermediate flex file consists data records of one 4-day interval,
with the last record indicated by a negative interval number.
Data records are fixed-blocked by a factor of 10. Physical records are
5880 bytes in length. Logical records are 588 bytes(147 words) in length.
