Spectral energy distribution for radio source VLA1. Diamonds correspond to the VLA high-angular resolution flux measurements listed in Table 5. The triangle corresponds to the 20 cm flux measurement in Table 4. The dashed line shows the linear fit (S_ν ∝ ν^α) to the high-angular resolution data (diamonds) with α = −0.19. The solid line shows a homogeneous Hii region fit to all the data points in the figure.
