IBEX uses the Earth's orbital motion and repointing of the spacecraft
to make periodic full maps of ENAs from the heliosphere.
The IBEX Science Team will release data related to these new maps as
soon as they are validated.
The data and documentation for them can be found
on links on this page.

Please note:
IBEX sky maps, calibration data, and other products posted here
are continually evolving and being improved as we learn
more and improve our analysis techniques. The IBEX team is delighted
to work with outside scientists who want to work with IBEX data; we
urge you to email us
at ibex_datareleases@lists.sr.unh.edu and collaborate directly with the IBEX Science Team.
Data Release 1
Time Series Data
The
Time Series data files
contain the count rates seen by the
IBEX sensors in both direct event (DE) and histogram (HB) modes.
The documentation file explains the details.
The Time Series data can be accessed by clicking
here.
Map Data
The
IBEX Map data files
plot the IBEX Hi and Lo flux rates onto the celestial sphere, in J2000
ecliptic coordinates. The flux maps are sums over a six-month period
(orbits 9-31) and are broken out by sensor energy band (Hi bands
2-6, Lo bands 5-7).
Also included are plots of Hydrogen and Oxygen rates based on time-of-flight
measurements.
The Maps data can be accessed by clicking
here.
Calibration Data
The
Calibration Data files
give all information about the IBEX
sensors required to understand the collected data.
The calibration data can be accessed by clicking
here.
The documentation file explains the details.
Data Release 2
The
IBEX second data release consists of maps of the heliosphere in two
epochs, plus maps made from the combination of the two epochs. The data
release also contains a preprint of McComas et al. 2010, "The evolving
outer heliosphere: Large-scale stability and time variations observed by
the Interstellar Boundary Explorer".
The maps provided in the second data release were made using data taken
taken with the IBEX Hi sensor in its energy bands 2 through 6. The first
epoch's maps, found in directories Map1 and Map1_CG, were made using data
from orbits 11 through 33 (December 2008 through June 2009); the second
epoch's maps, found in directories Map2 and Map2_CG, were made using data
from orbits 34 through 56 (June 2009 through December 2009). The combined
maps were made with data from orbits 11 through 56.

here.
Data Release 3
The IBEX third data release
contains data used in the publication of Moebius et al., 2012,
"Interstellar Gas Flow Parameters Derived from IBEX-Lo Observations in
2009 and 2010 - Analytical Analysis" and Bzowski et al., 2012,
"Neutral interstellar helium parameters based on IBEX-Lo observations
and test particle calculations".
The data are the 6 degree resolution corrected histogram data and the
observation time periods in one csv file for each orbit for both the
angular fit analysis and the count rate analysis.
The IBEX fourth data release contains data used in the publication of
McComas et al., 2012,
"The First Three Years of IBEX Observations and Our Evolving
Heliosphere".
IBEX results, together with in situ observations from
the Voyager-1 and -2 spacecraft currently in the inner heliosheath,
other supporting observations from several spacecraft, and a broad
theory and modeling effort are producing a revolutionary new
understanding of the outer heliosphere and its interactions with the
local interstellar medium. In this release, we provide new ENA
observations from IBEX, covering its first, second and third years of science
operations.
