This comes out of #509, which introduces a function that computes and assigns `mask`'s to `Spectrum1D` objects. This led to a discussion where it was realized that a lot of the downstream analysis ta…

**Describe the bug**
All attempts to fit a model using the Model Fitting plugin in Mosviz fail, for even
the simplest model (Constant1D), to either the full Dataset or a Subset. The fol…

My work to make PAHFIT run on spectral cubes is in a separate repo: https://github.com/drvdputt/PAHFIT-cube.
The readme is quite outdated though. I initially tried some things based on a set of Spi…

It was not necessary to recode mpfit for Python. The same algorithm is available in scipy.optimize.leastsq
hope this is helpful

As the attenuation law is not universal, one should use a model allowing different UV slope, 2175 bump strength whenever the spectral coverage allows it. For this purpose, one of the most used recipe …

I am seeing significant differences between the EXAFS spectra data from Larch and Athena as well as differences in the fitting results. I assumed that there would be minor differences between fitting …

Updated version of Kurucz models - including good wavelength coverage in the JWST range.
Ideally would replace CK04. Need to pick a reasonable resolution. And decide on what to do with the extra gr…
