256-Channel Pulse Height Analyzer Data


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

Time span: 1972-04-21 to 1972-04-25


This data set, which was submitted by the experimenter, contains reduced pulse height analyzer data from the 256-channel pulse height analyzer, alpha particle spectrometer in chronological order. The data are on binary magnetic tape generated on an IBM 360 computer. There are a variable number of physical records, wiht 20 logical records per physical record, and each logical record is 48 8-bit bytes in length. Each logical record corresponds to one sec of spacecraft telemetry, i.e., to one of the good records in the unreduced telemetry tape. A "good" unreduced telemetry record is one that has no more than 19 "bad" data flags set. Each record contains the time, three temperature measurements, data flags, 10 pulse height channel numbers and detector identification for each, and several housekeeping parameters.
