10-Minute Average Summary Data

Description

These 10-minute averaged summary data are on magnetic tape created on an IBM 360/91 computer in binary. Each physical block contains 61 logical records of 520 bytes (130 real words). The logical records each contain time in year, month, day, and ms of day; frequency channel zero count; number of non-zero points of the frequency in the 10-min interval; 2% minimum and maximum of the points below the value of 10* log t (time) calibrated; mode (most frequently found) and median of value of 10* log t calibrated; and 100* log (sigma t) linear sum. These calculations are repeated for 16 channels within the logical record.
