Resumen:
We have used the radio continuum survey data at 408, 1420 , 22800 and 33000 MHz in order to study the spectral index distribution in the Gum nebula region. After subtraction of the underlying thermal emission, we have applied the tomography technique and we found variations in the radio continuum temperature spectral index between the IRAS Vela shell (IVS), that is a prominent ring-like feature, and the Gum nebula. These results would provide further support to the idea that both structures are different.
