Just a brief comment. At first sight it looks like a good start.
However, how do you deal with bad data/ Suppose I flag a part of the
spectrum as bad. Is your formalism capable of handling that?
It would be nice if there were s spectral library that could be used to fit
to. For example a stellar one (Pickles) and a galaxies one (forgot the
Similarly, if you have models for a Star+disk, or binary, that would be
nice to have to fit to.
When measuring lines, it would be nice to have line ratios of (effectively)
optically thin lines from the same upper level to work with. That is useful
both for seeing if the line identification is good and estimating optical
But so far, this is the best I've seen pythonic wise. (and that may just be
because I don't know much)....
