This test ODF is an observation of nine point sources. Five form an F shape, and the other four form a smaller F shape with the middle source of the large F. The cluster extends over 0.25 degrees. Each source has a narrow Gaussian line spectrum, each around its own energy (1 keV, 2 keV up to 5 keV). These sources are observed with a spacecraft that is initially pointing to the source in the center and is drifting slowly during the observation.
