Reduced Cosmic-Ray Count Rate and Orbital Data Merged


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1967-07-28 to 1969-02-02


This data set, provided by the principal investigator, consists of reduced cosmic-ray count-rate data merged with orbital data and corresponds to the time period before the spacecraft went into a spin mode. The data are on binary magnetic tapes written on an IBM 360/75 computer. The data include a 20-word file header record followed by a variable number of physical records (each having a 6-word record header). There are a variable number of logical records per physical record, since the 98-word orbital data logical record was inserted into the stream of four-word count-rate data logical records once every minute. This insertion did not necessarily occur at the beginning or end of a given physical record. Each file contains about 5 min of data. The tapes contain all counting rates, universal time, telescope temperatures, latitude, longitude, height, sun-earth-satellite angle, geomagnetic coordinates, and various data-quality flags. The data within a file are always monotonically increasing in time. However, the set of files comprising a data tape is not necessarily time ordered. Redundancies in the data have been deleted.
