Total integrated spectrum for the S-shaped component and each radio lobe in G29.37+0.1. The flux density measurements made using the new GMRT image are indicated by an open symbol. The straight line represents a weighted fit with a power law index α = 0.59 ± 0.09 to the data points measured in the S-like feature. No fit was performed to the flux density estimates in both radio lobes (the dashed line between points is only a reference to the reader).
