Radio LCs of SN 2004gq at 8.5 GHz (top panel), at 4.9 GHz (middle panel), and at 1.4 GHz (bottom panel). The red dots show the observational data at the specified frequency, and the red triangles show the upper limits of the observations, which were not included in the model fits. The green lines represent the best-fit “pure” thermal FFA model, and the black lines represent the best-fit “pure” nonthermal SSA.
