IBEX High Energy Neutral Atom Imager (ENA-Hi) Data Release 10, Compton-Getting corrected, not Survival Probability corrected, Omnidirectional, West Longitude Ecliptic Maps, 6 month averaged data, Level H3

Description

This IBEX-Hi data set is from Release 10 of all-sky map data for the first seven years, 2009-2015, in the form of omni direction Hydrogen, H, energetic neutral atom fluxes with Compton-Getting corrections for spacecraft motion and with no corrections for ENA survival probability between 1 and 100 AU. All-sky maps have been compiled for each consecutive 6 month time interval. 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-Hi and/or IBEX-Lo data covering 2009-2017. The data consist of all-sky maps in Solar Ecliptic Longitude, east and west, and Latitude angles for Energetic Neutral Atom, ENA, Hydrogen fluxes from IBEX-Hi from energy band 2 through energy band 6, see the first table below, in numerical data form. This particular data set is from IBEX Release 10 which includes observation from the first seven years, 2009-2015, of the IBEX mission. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D.J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 The IBEX-Hi band/channel center energies and full width half maximum, FWHM, energy ranges are listed in a table below: +-----------------------------------------------------+ 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 +-----------------------------------------------------+ This particular IBEX-Hi CDF data product was constructed from the original ascii files named using the pattern hvset_cg_mapN for N=1,14, includes pixel map data from the omni direction, with corrections, cg, for the Compton-Getting effect no corrections, nosp, for ENA survival probability between 1 AU and 100 AU, and a map compilation cadence equal to 6 months. In all, there are 12 IBEX-Hi Release 10 CDF data products resulting from the multiplication of options for two Compton-Getting correction settings by two survival probability settings by three directional settings: antiram, ram, omni. The table below defines how the file naming pattern is constructed for each data product. Note that "ibex_h3_ena_hi_r10" is the file naming pattern root for all twelve of these IBEX-Hi CDF data products. The asterisk symbols in the last column of the table shows the line corresponding to this CDF data product within the expanded file naming pattern schema. +-----------------------------------------------------------------------------------------------------+ C-G Corr.

C-G corrections account for how ENA measurements are affected by the the orientation of the IBEX spacecraft velocity vector relative to the arrival direction of the ENAs. cg: Compton-Getting corrections applied nocg: Compton-Getting corrections not applied The second column in the above table shows whether Survival Probability, SP, corrections have been applied to the data. SP corrections 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. sp: Survival Probability corrections applied nosp: Survival Probability corrections not applied The third column in the above table shows the constraint placed on the ENA arrival direction relative to spacecraft motion used in the construction of each of the various IBEX-Hi Skymaps. omni: All data, no Constraint on the IBEX velocity vector relative to the ram direction of incoming ENAs ram: Data constrained to times when the IBEX velocity vector pointed into the ram direction of the incoming ENAs antiram: Data constrained to times when the IBEX velocity vector pointed away from the ram direction of the incoming ENAs The data in IBEX Release 10 are separated into 6 month and 1 year segments. The following table shows the association between Release 10 map numbers from 1 to 14 with mission year from 1 to 7, orbits from 11 to 310b, and dates from 2008-12-25 to 2015-12-23. +-------------------------------------------------------------------------+ Skymap # Year Start-End of Orbit or Arcs Start Date to Stop Date ------------------------------------------------------------------------- 1 1 11-34 2008-12-25 to 2009-06-25 2 1 35-58 2009-06-25 to 2009-12-25 3 2 59-82 2009-12-25 to 2010-06-26 4 2 83-106 2010-06-26 to 2010-12-26 5 3 107-130a 2010-12-26 to 2011-06-25 6 3 130b-150a 2011-06-25 to 2011-12-24 7 4 150b-170a 2011-12-24 to 2012-06-22 8 4 170b-190b 2012-06-22 to 2012-12-26 9 5 191a-210b 2012-12-26 to 2013-06-26 10 5 211a-230b 2013-06-26 to 2013-12-26 11 6 231a-250b 2013-12-26 to 2014-06-26 12 6 251a-270b 2014-06-26 to 2014-12-24 13 7 271a-290b 2014-12-24 to 2015-06-24 14 7 291a-310b 2015-06-24 to 2015-12-23 +-------------------------------------------------------------------------+
