I have noticed that propagate is having and issue with the XSPEC absorption models.
I have a model that looks like this:
`spectral_model = XS_phabs()* XS_zphabs() * XS_powerlaw()`
I do a fi…

## Summary
I am unable to fit user defined models with a user defined fit statistic calculation in Sherpa version 4.9.0. This works using version 4.7, but stopped working in all versions starting w…

After doing a clean install of astromodels, I'm having an issue with passing multiplicative models to 3ML's Model class. From the 3ML joint XRT demo:

One of the major areas that I did not cover when converting CIAO's ahelp documentation into the docstrings is that of the models. We should do this.
I have started this on a branch: `feature/add-mode…

When wanting to make multiplicative composed spectral components (e.g. Band*Exponential_Cutoff), the overall unit also becomes the multiplication of those units. Attempting to change the normalizatio…

While using the 11/15 CIAOD build, a name error is thrown when a template model is fitted using the "gridsearch" method's default setting where no sequence is set in Python 3. In Python 2, there's no…

When running the example **Joint fitting XRT and GBM data with XSPEC models**, I am no longer able to fix the values of XSPEC functions. It appears as if they are only floats and not model objects:
