5.46-Min Averaged Experiment-Mode Count Rates


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1973-10-30 to 1997-02-02


This data set consists of time-ordered, reduced, 5.46-min particle count accumulations from the main and low-energy telescopes written on binary magnetic tapes. Each file contains the same number of 2640-character physical records. Each physical record contains 15 logical records that contain the rate data for one time interval. The logical records contain time and experiment operation data, the earth-sun-spacecraft angle and geocentric distance, and the rate data for the 15 channels. Data quality, time coverage, and accumulated number of counts are given for each channel. Sectored rates are not provided, but the anisotropy and sector number of the maximum and minimum flux are given for the two lowest energy channels of the main telescope.
