My progress so far for this project has been in completing spectral analysis on 5 young stars. Phase one, in which I complete by-eye fittings of models to data on the give spectra using the PHOENIX da…

Gaussian Fitting is commonly used for fitting data like spectral line. (#22 is related issue)
This issue is to focus on the details and implementations of algorithms(a few kind of algorithms are in…

Right now the `QuantityModel` (as output by the fitting machinery) only accepts inputs with the *same* units as the spectrum.spectral_axis that was used to create it. It would be nice if it also reco…

In the low frequency end of the ALMA bands, there can apparently be measurable spectral slope, which invalidates the 'flat continuum' assumption implicit in all of statcont. We should include a way t…

According to https://lime-stable.readthedocs.io/en/latest/outputs/outputs1_measurements.html
the `v_r` output parameter contains the radial velocity (note that there are brackets missing in the defin…

When converting simulated PHA data from a `gdt.core.simulate.pha.PhaSimulator` object to a `gdt.core.pha.PHA` object using `gdt.core.simulate.pha.PhaSimulator.to_pha`, setting the energy_range attribu…

Hey, I wanted to ask if you planned on implementing the BCMultiTemplateFitter from the C++ version. Or if there is anything similar in the Julia version. This would be very useful when fitting multipl…

There are concerns that the current Stokes I fitting code may not be the best currently available (since it's based on the FORTRAN MINPACK-1 package from 1980). Some experimenting is needed to determi…

During the last coding sprint, @cgalelli and I tried to implement a generalised 1D model to
1. Avoid code duplication between temporal and spectral models
2. Enable an easy API for fitting other …

Fabio Acero talk at the Chandra Workshop presented the results of 3D spectral-spatial analysis of Cas A. He combined Sherpa (models and I/O) and gamma-py (3D) to perform the fitting. Sherpa needs to b…
