ctools

Hi Cosimo
I am under the impression that you can do what you want with the base models provided in ctools

• regarding the log-parabola defined in terms of beta * log10 (reference analysis) vs eta * ln (ctools), you can easily achieve your purpose with the standard ctools models; just remember that beta * log10 (E/E0) = beta/ln(10) ln(E/E0), therefore you can compare the ctools results with your reference analysis by a simple multiplication beta = eta * ln(10) (same goes for the uncertainty);
• for the log-parabola with exponential cutoff perhaps I’m missing your point, but isn’t what you are trying to define exactly what you get using the multiplicative type model (http://cta.irap.omp.eu/ctools/users/user_manual/models_spectral.html#multiplicative-model) with first component given by a log-parabola (http://cta.irap.omp.eu/ctools/users/user_manual/models_spectral.html#log-parabola) and the second component being the exponential (http://cta.irap.omp.eu/ctools/users/user_manual/models_spectral.html#exponential-model) of a power law with index fixed to 1?

Hi Luigi

sorry for the belated reply and thanks for the suggestions. I’ll try to implement it.

You can close the feature request,

Thanks again.
