Results of the 20 reconstructions from perturbed data to determine the robustness of the imaging methods for STIX. The gray contours show the 20 reruns, and the red contours are the average over all runs. The contour levels are 20-90% of the maximum values. For the images, we used the time range 15:24:28 UT to 15:25:16 UT (these times are corrected for the light travel time to Earth, about 198.8 s) and the energy range 22-28 keV.
