Picture of the Month

February 2002

The first images of a real X-ray source (Am 241) obtained with the two JEM-X instruments after installation on INTEGRAL.
The source is not an X-ray star, but a radioactive source suspended in a crane 5 meter above the satellite.
The image (using 30 keV escape peak photons) from JEM-X1 is green that from JEM-X2 is purple.
At 5 meter distance the two image fields only partly overlap, but the two instruments agree
within a couple of mm on the physical location of the source.
