This data set is from the IBEX-Hi Release 12 Count Data for Magnetospheric Imaging. This release provides data for various IBEX orbits from orbit 23 which started on 2009-03-26 to orbit 207b which ended on 2013-05-30. The data include 21 orbits from IBEX-Hi 6° histogram ENA count data, which is primarily what have been used in IBEX magnetospheric studies.
The Interstellar Boundary Explorer, IBEX, has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX ENA-Hi and/or IBEX ENA-Lo data covering 2009-2018.
The data consist of IBEX-Hi Count Data for Magnetospheric Imaging during instrument pointing in spin angle from 0° to 360° between the north and south Ecliptic poles. A spin angle equal to 0° corresponds to the north Ecliptic pole. Counts come from IBEX-Hi energy band 2 through 6:
+-----------------------------------------------------+
| Energy Band | Center Energy | Energy Range |
|-----------------------------------------------------|
| Channel 2 | ~0.71 keV | 0.52 keV to 0.95 keV |
| Channel 3 | ~1.11 keV | 0.84 keV to 1.55 keV |
| Channel 4 | ~1.74 keV | 1.36 keV to 2.50 keV |
| Channel 5 | ~2.73 keV | 1.99 keV to 3.75 keV |
| Channel 6 | ~4.29 keV | 3.13 keV to 6.00 keV |
+-----------------------------------------------------+
Background counts have not been removed. Counts are separated into 6° latitudinal bins, with each angle label representing the center of the bin.
Details of the data and enabled science from Release 12 are given in the following journal publications: McComas et al. 2011, 2012b; Fuselier et al. 2010, 2015; Petrinec et al. 2011; Ogasawara et al. 2013, 2019; and Dayeh et al. 2015.

For the first two and a half years of science operations, which corresponds to from Orbit 1 through Orbit 127), the IBEX orbital period was approximately 7.5 days and the spin axis was repointed once each orbit around perigee, leading to bands of sky viewing centered 7.5° apart. In June 2011, over Orbits 128 and 129, IBEX was maneuvered into a previously unknown, long-term stable lunar synchronous orbit with apogee still close to 50 Earth radii (McComas et al. 2011a). Since then, the IBEX orbital period has been approximately 9.1 days, which is one third of the lunar sidereal period of 27.3 days. Orbit numbers from 130 onward are split into two segments, 'a' and 'b'. Furthermore, starting in orbit segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and eliminated the lowest energy step, ESA1, in exchange for doubling the statistical sampling of ESA3, center energy ~1.1 keV.
