This test ODF is an observation of four point sources with an incident angle of 0.05 degrees and positioned in a square. Two have a Gaussian spectrum centered around 1 keV and 100 eV width, and two have a powerlaw spectrum between 10 eV and 10 keV with a slope of -1. Two are point sources, two are extended sources with a radius of 0.01 degrees. Two have a constant flux, one has a sinusoidal flux variation with a period of 10 s and one with a period of 30 s.
These sources are observed during 3 ks with the instrument in the default mode.
