JEM-X Gain Calibration Archive

The Joint European Monitor for X-Rays aboard the INTEGRAL satellite operated from launch on 17 October 2002 to mission end on 28 February 2025, across 2887 orbits of Earth. Comprising two identical X-ray detectors, it allowed for X-ray observations simultaneous with INTEGRAL's gamma-ray detections.

DTU Space led the JEM-X investigation in collaboration with research institutes across Europe. Read more about JEM-X here.

DTU Space provided gain calibration tables for both JEM-X detector units throughout the lifetime of the instrument. This data is essential for proper interpretation of the JEM-X data, so it is archived in its original form on this website. The main INTEGRAL data archives can be found at ESA here.
