… and subtraction from the left as well as from the right. This makes the manipulation of spectra through various operations slightly more flexible and easier for users, so they...
As commented on in #968 , it would be nice to have the math behind the uncertainty propagation in the analysis functions written out and documented. This might involve LaTeX...
This adds some minor improvements to the common Data Central loaders, which will be used in survey loader to come.
Simple enough, figured we should mention how to get the uncertainty in the fit parameters for non-default fitters.
Right now, LMFitter gives you error propagation, but similar results are not returned for the other fitters, which may have more complicated calculations. Error propagation should be considered in these...
I am trying to fit some multi-component spectral lines with unrestricted `Gaussian1D` models, but the fit sometimes does not converge. In some cases (like the image below), the fit seems...
At the time of posting this, `.write` is not mentioned at all in https://specutils.readthedocs.io/en/latest/spectrum1d.html except as a column in [the table](https://specutils.readthedocs.io/en/latest/spectrum1d.html#list-of-loaders), which mostly says "no" for most of the supported...
`analysis.correlation.template_logwl_resample` (which is called internally by `template_correlate`) defaults to `delta_log_wavelength=None` which in turn adopts the _smallest_ delta wavelength from the input array. If this smallest delta wavelength is particularly small,...
Description: I have a FITS file which is already wavelength calibrated and have spectral world coordinates in the Header. But when I try to read the file using this: `Spectrum1D.read(specdata.any(),...
