Parameter values and related uncertainties reconstructed by PSO (left column) and SMC (right column) from the visibility amplitudes measured on November 18, 2020 from 05:45:30 to 05:46:15 UT in the energy channels E₁, E₂, E₃, E₄, E₅, and E₆, which are identified in the abscissa by their weighted mean energies. From top to bottom: total flux and FWHM of the two sources and x and y coordinates of the center of the first source (the other one is symmetric with respect to the origin).
