Redmine ctools - Support #3071 (Closed): define a custom spectral modelhttps://cta-redmine.irap.omp.eu/issues/30712019-11-22T16:40:38ZNigro Cosimocosimonigro2@gmail.com
<p>Hello,</p>
<p>reading through the spectral components available in ctools<br /><a class="external" href="http://cta.irap.omp.eu/ctools/users/user_manual/models_spectral.html">http://cta.irap.omp.eu/ctools/users/user_manual/models_spectral.html</a><br />it seems that it is not possible to use a custom model.</p>
<p>What is available in this direction is just a Composite model assembled from the predefined models or a FileFunction that can only be scaled in amplitude.</p>
<p>As I am trying to reproduce some results from a paper I’d like to have a way to plug the exact same models in the likelihood analysis.<br />More specifically I would like to have a LogParabola with log10(E / E_0) in the second spectral index and a LogParabola with an exponential cutoff.</p>
<p>What would be the way to proceed?</p>
<p>Thanks for the support.</p>
