Description

Each record captures the counts of >~14 keV
protons arriving at the IBEX Background Monitor. Also included are
a time tag (seconds since 00:00 UT of January 6, 1980), an arrival
direction (R.A. and Dec. in J2000 celestial coordinates), and the
IBEX location. Data files are given for each 8-day orbit. The
data files are in ASCII.

Note
Data are planned for 6-month releases. However, Release_2 contained only IBEX-Hi map data. Extensions to later times for this data set may be forthcoming in the future. Relative to the given 1-sec cadence, this is a typical value. Intervals between ENA arrivals vary greatly.
