EP241021a broadband light curve. FXT observations are represented with green data points; optical observations are represented in shades of purple and pink; and radio data are represented in shades of blue. Inverted triangles indicate upper limits. The optical data represented with circles are taken from the literature (Busmann et al. 2025, 2024; Aryan et al. 2025; Fu et al. 2024a,b; Li et al. 2024; J-Jin et al. 2024; Pan et al. 2024; Ror et al. 2024; Kumar et al. 2024; Bochenek & Perley 2024a,b,c; Freeburn et al. 2024a,b; Quirola-Vasquez et al. 2024; Moskvitin & Spiridonova 2024a,b,c; Schneider & Adami 2024). The solid black lines and shaded-colored regions represent the best fit and the 500 best likelihood fits of the data using power law models.
