Telescope Accumulator Readings


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1967-05-24 to 1969-05-02


This data set contains cosmic-ray telescope accumulator count data on a binary magnetic tape written by an XDS 930 computer. Data set 67-051A-03F is an IBM 7094 version of this data set. The data are ordered by satellite orbit revolution number. Each file on the tape contains accumulator count data for one orbit and has a variable number of physical records (containing 816 binary words each). Each physical record has 102 sequences (logical records). Each sequence has eight words and contains detector accumulator counts, distance of satellite from earth, sequence number, and various data quality flags. Accumulator readings are given for each telemetered frame (5.12 s) for all nonoverlapped sequences (20.48 s) that contain at least one frame and for which data quality is considered good or fair.
