Included is a\ntime tag (seconds since 00:00 UT of January 6, 1980), an arrival\ndirection (R.A. and Dec. in J2000 celestial coordinates), the IBEX\nlocation, ENA energy band and coincidence type.  Positive species\nidentifications are not made, but most arriving ENA's are hydrogen\natoms.  Data files are given for each 8-day orbit and for each \nof the 6 IBEX-Hi energy bands.  The data files are in ASCII.",
