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.

Descriptions of the IBEX mission and sensors published in Space Science Reviews can be downloaded here:

• The IBEX Mission
• The IBEX Hi Sensor
• The IBEX Lo Sensor

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 contact us (email Nathan Schwadron, n.schwadron@unh.edu) and collaborate directly with the IBEX Science Team.

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.

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 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.

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.
