Extended Data Fig. 4: Broken power-law fit to the early-time photometry of SN 2023ixf.
(a): Separate fitting to the t < 0.4 day (dark gray region) and 0.4 d < t < 3.0 day (gray region) phases of the early-time light curves of SN 2023ixf with \(f\propto {(t-{t}_{0})}^{n}\) model, with the best fitting curves represented as dotted and dashed lines, respectively. The g- and V-band light curves are shifted vertically for better display. The shifted values are shown in the legends. The error bars indicate 1-σ uncertainties of magnitudes. (b): The residuals relative to the best fittings.
