This is the entire data set returned from the ICE/ISEE-3 X-ray spectrometer. The measured parameters are photon counting rates in the energy range from 5 keV to 3 MeV. The data set consists of 9 Exabyte (8-mm) tape cassettes. The data are stored in "tar" format in one file per day, starting 12 Aug. 1978 and ending 7 Feb. 1987. Each tape contains about 300 days of data. A full day-long file takes up ~ 3 MB. In compressed form on the tape, it occupies ~ 2 MB. Users should obtain the software provided by the PI for handling and analyzing the data, with NSSDC ID 78-079A-14F. This software includes a utility named x_datafile for selecting, extracting and decompressing a desired data file from the Exabyte tapes. The spacecraft was in a heliocentric orbit at the Lagrange libration point between the Earth and Sun until 1984, when the spacecraft was renamed ICE and sent to rendezvous with a comet. Consequently, use of the data requires proper time correction from satellite time to Universal Time (UT), as well as other special corrections described in the users' guide. For a detailed discussion of the instrument, see K. A. Anderson, S. R. Kane, et al., IEEE Trans. on Geosci. Electron., vol. GE-16, no. 3, July 1978.
