IBEX High Energy Neutral Atom Imager (Hi) Data Release 16, Compton-Getting corrected, Survival Probability corrected, Antiram direction, West Longitude Ecliptic Maps, Level H3 (H3), eleven year average Data

* 1: 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 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019.\n* 2: This data set is from the Release 16 (11-year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU.\n* 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication:\n* 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.),\n* 5: http://doi.org/10.3847/1538-4365/aa66d8\n* 6. The following codes are used to define dataset types:\n- cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs.\n- nocg = no Compton-Getting corrections\n- sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular.\n- noSP - no survival probability corrections have been applied to the data.\n- omni = data from all directions.\n- ram = data was collected when the spacecraft was ramming into the incoming ENAs.\n- antiram = data was collected when the spacecraft was moving away from the incoming ENAs.\n* 7.
