Solar Wind Plasma (UADS-LFD File) Data

Description

These Unified Abstract Data System (UADS), low frequency data are on mixed-mode magnetic tape created on an IBM 360 computer. The first file on each tape provides a readily available description of the data contained in the tape's second and third files. It contains a variable number of 80-character EBCDIC records. File 2 contains status information for the 9 experiment data sets contained on the tape. There is one 266-character EBCDIC record for each orbit included on the tape. The third file consists of a variable number of binary 396-byte logical records. There are 301 logical records per orbit of data. These records contain the processed orbital data centered around periapsis sampled at approximately 12-s intervals. The first logical record for each orbit contains the data for all of the instruments' variables sampled at the UT start time specified for the orbit in its status record (file 2). Record 151 contains the variables' data sampled at the time of periapsis, as specified in the orbit's status record. The first 4 bytes of a record act as a key, giving the record's orbit and nominal time relative to periapsis. The tapes contain data for the following experiments data sets: Electron Temp. Probe (-01A), Radar Altimeter (-02B), Retarding Potential Analyzer (-07A), Neutral Particle Mass Spectrometer (-11A), Triaxial Fluxgate Magnetometer (-12A), Electric Field Detector (-13A), UV Spectrometer (-15B), and Ion Mass Spectrometer (-17A), and solar wind plasma analyzer (-18C). They will be described identically under each ID.
