Spectral energy distributions fitted with a blackbody model. Each panel shows a SED of SN2019wxt (circles represent detections with one-sigma error bars; triangles represent upper limits) constructed by considering photometric measurements binned within a time window (annotated above each panel, in days post i-band maximum). The formally best-fitting blackbody is shown by a solid line, while the filled regions span the 16th to the 84th percentile (equivalent to one-sigma uncertainties) of the model magnitudes corresponding to the posterior samples at each wavelength. The fits are performed adopting a log-uniform prior on the BB luminosity in the 10³⁵ − 10⁴³ erg/s range and a uniform prior on the temperature in the 1000 − 20 000 K range.
