Scatter plots of the real and the imaginary parts of the relative visibilities for each sub-collimator for the non-thermal (left 3 columns; 32 – 76 keV; 05:13:01 – 05:13:09 UT) and thermal (right 3 columns; 15 – 18 keV; 05:14:42 – 05:14:50 UT) emission. (Times represent light arrival time at Solar Orbiter.) Each point corresponds to a 1s integration time and is colour-coded in time from violet to red. Error bars represent 1σ uncertainties. The black dashed lines represent the x = 0 and y = 0 lines, while the grey circles centred at the origin help highlight changes in the relative visibilities’ amplitudes and phases.
