Comments:
The radio spectrum is classified as compostie T + NT by Montes et al. (2009), but the spectral index of 0.46 +/- 0.05 does not fulfill the criteria adopted here (lower than about 0.3). One can not therefore reject the scenario where the low value of the spectral index could be explained by a thermal contribution coming from the wind-wind interaction region.
