Combined kinematic fit from 15 GHz, 23 GHz, and 43 GHz for component 1, 2, and 3. The solid line indicates the best fit. For component 1, the dash-dotted lines represent the 1σ fit bounds, and the shaded area in the background reflects the confidence range of the fit. The time of arrival of the neutrino event IC220225A is indicated by the dashed red line and coincides with the passage of component 1 through component 3.
