Extended Data Fig. 3: A representative set of light curve and color curve models from the STARDUST2 classification algorithm.

From: A gravitationally lensed supernova with an observable two-decade time delay

Extended Data Fig. 3

Panels a-f show F105W and F160W, as indicated, plotting the model light curves in black and photometry as red markers. Panels g-i show the F105W-F160W color curves and color data. All data points as shown have been corrected for magnification and shifted in time using the preferred LENSTOOL model (model E, described in Methods: Lens Modeling). Plotted error bars include the measurement uncertainty and the lens modeling magnification uncertainty. Data points in the right column also include this magnification uncertainty, even though cluster-scale lensing is achromatic, because the STARDUST2 analysis was done on the light curve data, not the color data directly. In all panels the first data point is SN image 2, followed by image 1 and image 3. In each panel the black curves show 200 SN light curve models drawn at random from the nested sampling sequence of the STARDUST2 (sncosmo) classification.
