30 Minute Counts of All Detectors, ASCII


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

Time span: 1967-07-18 to 1973-06-23


This data set was created at NSSDC by converting 30-minute summaries of all detectors binary data set (PSFP-00021) to ASCII. This data set consists of beginning and ending year, day, and day fraction for each record, and electron, proton, and alpha particle count data summed over 30-min time intervals for each Geiger-Mueller and silicon solid-state detector. The record contents are the same as in the binary data set, except that Jan 1 is now day 1 (originally Jan 1 = day number 0).
