Fig. 1a and b. a Radio spectrum of Haro 1. The solid line is a fit of a combination of thermal and nonthermal power law spectra, the dashed line is a fit of a straight power-law. The data points for 1.489 GHz and 8.44 GHz are from this work, the others are from Klein, Wielebinski and Beck (1984) and Klein et al. (1991). b Radio spectrum of Mkn 314. The fit shown is a straight power-law. Data points not listed in Table 5 are from Klein et al. (1991).
