Hi everyone,
I'm having an issue with the modelling interface. I'm modelling the PSD of an X-ray binary trying to identify and subtract the QPOs from the broadband noise, and the issue I'm having is that when fitting the PSD the modelling bounds I'm imposing are neglected by the fit. As a result I get unphysical results and/or poorly constrained parameters (such as negative normalisations of components that should be additive).
I have uploaded a tarball including one of the lightcurves I'm working on and a Jupyter notebook to replicate the issue here: https://drive.google.com/file/d/1k8D-4F4h0H98D5fIqYTxBvcEqSWbTkLi/view?usp=sharing
