Particle Count Rates

Description

This experimenter-supplied data set consists of cosmic-ray count rate data interspersed with ephemeris data on GE 635 binary magnetic tapes. Data set 69-053A-01C contains an IBM 7094 version of this data set. The data records consist of 10 36-bit computer words, with each word being further broken down into integer numbers of spcified meanings. Data for one experiment sequence (10.23 s) are found in one record and include: (1) time (UT) clock data, (2) counts for each of the five registers for one sensor coincidence mode, and (3) data quality flags related to the noisiness of bit transmission. The ephemeris records consist of 20 36-bit words, 19 of which are floating point. Ephemeris records occur once each 1 or 10 min according to whether the spacecraft radial distance is < or > 42,000 km. Ephemeris data include spacecraft radial distance, geographic latitude and longitude, inertial ecliptic declination and right ascension, GSE and GSM Cartesian coordinates, and B and L. From June 21, 1969, to August 15, 1970, there are no data gaps > 24 h. There is one gap > 6 h and seven gaps > 2 h.
