Top: extinction-corrected UV/optical/NIR lightcurve of TDE 2025abcr, alongside a blackbody fit to the data described in Section 4.1.1. The lightcurve is well described by a single blackbody with a linearly evolving temperature. Lower left: 1σ uncertainty contour for the best-fit peak temperature and cooling rate. The temperature appears to change very little over time. Lower right: inferred blackbody radius as a function of time. The shaded region corresponds to the envelope of inferred radii when sampling the 1σ peak temperature/cooling ellipse.
