I'm using the naima tool to model radio and gamma-ray data from a supernova remnant.
I assumed the ECPL function to describe the particle distribution for a pure leptonic model by considering synchrotron, inverse Compton and bremsstrahlung emission processes.
The fit seems to correctly work (without warning or errors), also the related diagnostic plot is ok, but when I plot the SEDs of each process, the bremsstrahlung one shows strong oscillations at the lower energies that I can’t get rid of by changing the parameters. I attached here the model and SEDs plots:
I would ask you if it is a normal response of the software, which numerically fails for the bremsstrahlung process at these frequencies, or if it can indicate that I am doing something wrong.
