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 code. Each physical block contains 61 logical records of 520 bytes (130 real words). The logical records each contain time in year, month, day, and millisecond 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 from the value of 10* log T 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.
