IBEX-Hi Direct Events

ResourceID

spase://NASA/NumericalData/IBEX/Hi/Direct_Events

Description

Each record captures the characteristics of one energetic neutral atom arriving at IBEX-Hi. Included is a time tag (seconds since 00:00 UT of January 6, 1980), an arrival direction (R.A. and Dec. in J2000 celestial coordinates), the IBEX location, ENA energy band and coincidence type. Positive species identifications are not made, but most arriving ENA's are hydrogen atoms. Data files are given for each 8-day orbit and for each of the 6 IBEX-Hi energy bands. 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.
