SMC reconstruction from the visibility amplitudes observed by STIX at 05:46:30 UT on November 18, 2020, with one second integration time in the energy channel 7–12 keV. Top left: flaring source modeled by means of a double-Gaussian input configuration. Top right: corresponding data fit. Bottom: histograms for the FWHM and flux probability distributions for the two sources. In red, we show the mean and standard deviations of the posterior distributions (used to give point estimates).
