Merged L-Ordered Count Rates


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1959-08-07 to 1964-05-27


This electron and proton count rate and ephemeris data set is on one BCD magnetic tape that was generated at NSSDC on an IBM 7094 computer. These data are an L-value sorted version of the Geiger-Mueller (GM) tube and ion chamber count rate data found in data set 59-004A-03C, merged with ephemeris information from data set 59-004A-00D. Data are presented for the following L values: 2.0, 2.2, 2.4, 2.6, 2.8, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, and 8.0. Data from the GM tube and the ion chamber are presented in separate files. Each 84-character logical record contains the count rate, ratio of the magnetic field strength to the equatorial magnetic field strength (for the same L value), local time, universal time, month, day, year, geographic longitude and latitude, and L value.
